Electromagnetic surface modes are present at all surfaces and interfaces between material of different dielectric properties. These modes have very important effects on numerous physical quantities: adhesion, capillary force, step formation and crystal growth, the Casimir effect etc. They cause surface tension and wetting and they give rise to forces which are important e.g. for the stability of colloids. This book is a useful and elegant approach to the topic, showing how the concept of electromagnetic modes can be developed as a unifying theme for a range of condensed matter physics. The author concentrates in finding out the basic origin of the force and how they are developed from the collective excitations of the solids. Different materials are treated, e.g. metals, semiconductors, plasmas, liquids and gases all with different collective modes. In close relation to the theoretical background, the reader is served with a broad field of applications. The book serves readers who are concerned with applications to real world problems with a deep knowledge on surface modes, and inspires new developments of the field.

For decades, the surface-plasmon-polariton wave guided by the interface of simple isotropic materials dominated the scene. However, in recent times research on electromagnetic surface waves guided by planar interfaces has expanded into new and exciting areas. In the 1990's research focused on advancing knowledge of the newly discovered Dyakonov wave. More recently, much of the surface wave research is motivated by the proliferation of nanotechnology and the growing number of materials available with novel properties. This book leads the reader from the relatively simple surface-plasmon-polariton wave with isotropic materials to the latest research on various types of electromagnetic surface waves guided by the interfaces of complex materials enabled by recent developments in nanotechnology. This includes: Dyakonov waves guided by interfaces formed with columnar thin films, Dyakonov-Tamm waves guided by interfaces formed with sculptured thin films, and multiple modes of surface-plasmon-polariton waves guided by the interface of a metal and a periodically varying dielectric material. Gathers research from the past 5 years in a single comprehensive view of electromagnetic surface waves. Written by the foremost experts and researchers in the field. Layered presentation explains topics with an introductory overview level up to a highly technical level.

Modern Problems in Condensed Matter Sciences, Volume I: Surface Polaritons: Electromagnetic Waves at Surfaces and Interfaces describes the basic properties of surface polaritons and the methods of generating these waves in the laboratory at frequencies of interest to condensed matter physicists. The selection first elaborates on surface phonon polaritons in dielectrics and semiconductors and surface exciton polaritons from the experimental viewpoint. Discussions focus on interface polaritons; surface vibrations in anisotropic crystals; experimental methods for the excitation and study of surface polaritons; and surface vibrations in isotropic crystals. The publication then ponders on surface electromagnetic wave propagation on metal surfaces; thermally stimulated emission of surface polaritons; and effects of the transition layer and spatial dispersion in the spectra of surface polaritons. The text takes a look at surface polaritons at metal surfaces and interfaces and resonance of transition layer excitations with surface polaritons. Topics include resonance of the film phonon with the substrate surface phonon polaritons; investigations of surface modifications in ultra-high vacuum; and use of surface plasma waves for the investigation of solid-liquid and solid-solid interfaces. The selection is a dependable reference for physicists and engineers wanting to conduct research on surface polaritons.

This volume is based on lectures and contributed papers presented at the Eighth Course of the International School of Materials Science and Tech nology that was held in Erice, Sicily, Italy at the Ettore Majorana Centre for Scientific Culture during the period 1-13 July 1985. The subject of the course was "Electromagnetic Surface Excitations". Forty lectures were given by eleven distinguished scientists and engineers from France, Italy, the United Kingdom, and the United States. In addition to the lectur ers, approximately fifty participants representing eleven different countries throughout the world t. ook part in the course. Short contributed papers were presented by seventeen participants on the results of their own re search. The subject of the Course is of great importance for both pure science and for practical applications such as telecommunications. A technolog ical revolution is occurring in which the transmission of information by means of electrical currents travelling in copper wires is being replaced by transmission by means of light travelling in objects known as optical wave guides. The manipulation and processing of the light signals prior and subsequent to transmission through the wave guide has resulted in a technology often referred to as integrated optics. Important to the opera tion of integrated optics devices is the behavior of electromagnetic waves near surfaces and interfaces. One of the goals of the course was to further the dialogue between engineers and physicists in common areas of interest related to the propagation of electromagnetic waves along surfaces.

This book provides a general formalism for the calculation of the spectral correlation function for the fluctuating electromagnetic field. The procedure is applied to the radiative heat transfer and the van der Waals friction using both the semi-classical theory of the fluctuating electromagnetic field and quantum field theory. Applications of the radiative heat transfer and non-contact friction to scanning probe spectroscopy are presented. The theory gives a tentative explanation for the experimental non-contact friction data. The book explains that radiative heat transfer and the van der Waals friction are largely enhanced at short separations between the bodies due to the evanescent electromagnetic waves. Particular strong enhancement occurs if the surfaces of the bodies can support localized surface modes like surface plasmons, surface polaritons or adsorbate vibrational modes. An electromagnetic field outside a moving body can also be created by static charges which are always present on the surface of the body due to inhomogeneities, or due to a bias voltage. This electromagnetic field produces electrostatic friction which can be significantly enhanced if on the surface of the body there is a 2D electron or hole system or an incommensurate adsorbed layer of ions exhibiting acoustic vibrations.

A surface mode is an electromagnetic field distribution bounded at a surface. It decays exponentially with the distance from the surface on both sides of the surface and propagates at the surface. The surface mode exists at a metal-dielectric interface as surface plasmon (1) or at a photonic crystal surface terminated properly (34; 35; 36). Besides its prominent near-filed properties, it can connect structures at its propagation surface and results in far-field effects. Extraordinary transmission (EOT) and beaming are two examples and they are the subjects I am studying in this thesis. EOT means the transmission through holes in an opaque screen can be much larger than the geometrical optics limitation. Based on our everyday experience about shadows, the transmission equals the filling ratio of the holes in geometrical optics. The conventional diffraction theory also proved that the transmission through a subwavelength circular hole in an infinitely thin perfect electric conductor (PEC) film converges to zero when the hole's dimension is much smaller than the wavelength (40). Recently it is discovered that the transmission can be much larger than the the filling ratio of the holes at some special wavelengths (41). This cannot be explained by conventional theories, so it is called extraordinary transmission. It is generally believed that surface plasmons play an important role (43; 44) in the EOT through a periodic subwavelength hole array in a metallic film. The common theories in literatures are based on these arguments. The surface plasmons cannot be excited by incident plane waves directly because of momentum mismatch. The periodicity of the hole arrays will provide addition momentum. When the momentum-matching condition of surface plasmons is satisfied, the surface plasmons will be excited. Then these surface plasmons will collect the energy along the input surface and carry them to the holes. So the transmission can be bigger than the filling ratio. Based on this picture, they deduced naturally that when surface plasmons momentum-matching condition is satisfied, the surface plasmons are excited sufficiently and the transmission reaches its peak. I present a new theory from first principles to explain EOT through one-dimensional periodic subwavelength metallic slits in this thesis. This theory can also be extended to 2D hole arrays. I define the incident wavelengths that satisfy the momentum-matching condition as surface resonant wavelengths. I proved analytically that the transmission is actually zero at the surface resonant wavelengths. The correct logic is: When the momentum-matching condition is satisfied, the surface plasmons excited by each slit interfere constructively with each other, the total surface plasmons will go to infinity. But the law of nature forbids the infinity. The only solution is the surface plasmon excited by one slit is zero and all the energy is reflected. In my theory, the term corresponding to surface plasmons appear explicitly in the equations. So it confirms the importance of surface plasmons without any doubt. The theory divides the transmission process into two steps: energy collection process along the input surface and the propagation process in the slits. In the first process, the surface plasmons collect the energy along the input surface and carry them to the slits. This process happens efficiently at any wavelength other than the surface resonant wavelengths. So EOT can happen at almost any wavelength. After the energy enter the slits, the Fabry-Perot interference between the input and output surface decides how much energy is emitted from the slits. So the EOT wavelengths are decided by the Fabry-Perot resonances. I also use my theory to explain the data in literatures. The transmission spectra through 1D slits or 2D hole arrays in literatures agree with my theory very well. The new theory can explain a lot of experimental results published recently, such as the transmission through randomized hole arrays, the strong influence of the hole shape on the transmission peaks, and so on. Beaming is another far-field effect resulting from surface modes. Normally light coming from a subwavelength waveguide is diffracted to all angles. With the help of surface modes, we can confine the output field in a small angle interval. This phenomenon is called beaming (46). The principle of the beaming has been explained clearly in literatures (47). To achieve good beaming, a photonic crystal waveguide need a surface layer to support surface modes and a grating layer to coupling the evanescent surface modes into propagation modes. A metallic beaming structure is generally a subwavelength waveguide surrounded by periodic structures such as grooves or dielectric gratings (53; 54). The flat metal surface supports the surface mode, so additional surface layer is not necessary. The periodic structures work as the grating layer.
