The underlying principle of the radio frequency plasma probe is presented. The resonance properties of the probe's equivalent circuit with and without external magnetic field are analyzed. The admittance of the equivalent circuit is shown to posses a pole at the sheath hybrid frequency and a zero at the upper hybrid frequency. The phase of the admittance changes signature to become negative, in the range of frequency between the pole and the zero. Some significant experiments using radio frequency plasma probe for ionospheric research are briefly described.

Interactions of electromagnetic fields with materials at high frequencies have given rise to a vast array of practical applications in industry, science, medicine, and consumer markets. Applicators or probes, which are the front end of these systems, provide the field that interacts with the material. This book takes an integrated approach to the area of high frequency applicators and probes for material interactions, providing a toolkit for those who design these devices. Particular attention is given to real-world applications and the latest developments in the area. Mathematical methods are provided as design tools, and are often simplified via curve-fitting techniques that are particularly usable by handheld calculators. Useful equations and numerically solved examples, using situations encountered in practice, are supplied. Above all, this volume is a comprehensive and useful reference where the reader can find design rules and principles of high frequency applicators and probes for material processing and sensing applications. Electronic and electrical R&D engineers, physicists, university professors and students will all find this book a valuable reference. Mehrdad Mehdizadeh is with the DuPont Company, Engineering Research & Technology Division in Wilmington, Delaware. His areas of expertise include high frequency hardware and electromagnetic methods of processing, sensing, and characterization of materials. His work and innovation in industrial, scientific, and medical applications of radio frequency and microwaves has resulted in 19 US patents and a number of publications. He earned his Ph.D. and M.S. from Marquette University (1983, 1980), and a B.S. from Sharif University of Technology (1977), all in electrical engineering. Dr. Mehdizadeh is a Senior Member of the Institute of Electrical and Electronic Engineers (IEEE ), Sigma Xi (Scientific Research Society), the International Microwave Power Institute (IMPI ), and a voting member of IEEE Standard Association. Books in this area are usually theoretical; this book provides practical information for those who actually intend to design a system Features real world and numerically solved examples, and curve-fitted simple equations to replace complex equations provided in typical texts Author is a voting member of IEEE Standards Association

Microwave/RF Applicators and Probes for Material Heating, Sensing, and Plasma Generation, Second Edition, encompasses the area of high-frequency applicators and probes for material interactions as an integrated science. Based on practical experience rather than entirely on theoretical concepts, and emphasizing phenomenological explanations and well-annotated figures, the book represents one of the most important resources on the topics of microwave technologies, applications of RF and microwaves in industry (industrial heating and drying), and microwave engineering. After covering the basics of field-material interactions, the book reviews and categorizes probes and applicators, demonstrates their real-world applications, and offers numerically solved examples. Readers will find valuable design rules and principles of high-frequency applicators and probes for material processing and sensing applications in this expanded edition. Presents new information on how the interactions of electromagnetic fields with materials at high frequencies have given rise to a vast array of practical applications in industry, science, medicine, and consumer markets Thoroughly revised and expanded edition, providing an update on the most recent trends and findings Contains many new sections within existing chapters, along with new chapters on applicators for plasmas at microwave/RF frequencies

In order to ascertain the electron density in the earth's ionosphere by direct measurement a radio frequency (RF) impedance probe technique has proved useful. This technique involves monitoring the changes in impedance of an antenna mounted on a rocket or satellite vehicle traversing the inospheric regions of interest. The changes of antenna impedance can be related to the electron density of the surrounding plasma through use of suitable theoretical development of the antenna-plasma interaction. It is the purpose of this treatise to develop a more general expression for the impedance of an antenna in the ionosphere to be useful as an RF probe for measurement of electron density. The investigation of ionospheric plasma characteristics by means of such RF probes has received a great deal of attention since the advent of the rocket allowed direct measurements within the ionosphere.
