Although it is one of the oldest sectors of electronics and now somewhat taken for granted, radio frequency transmission literally changed our world. Today, it is still the backbone of myriad applications, from broadcasting to electronic counter-measures. The wide variety of hardware in use means that those working in the field must be familiar with a multitude of principles and applications, but finding an up-to-date, comprehensive source for this background material has been difficult, if not impossible. The RF Transmission Systems Handbook addresses the underlying concepts, operation, and maintenance of high-power RF devices, transmission lines, and antennas for broadcast, scientific, and industrial use. Focusing on devices and systems that produce more than one kilowatt of output power, the handbook explores the following major topics: Applications: The common uses of radio frequency energy Fundamental principles: The basic technologies, concepts, and techniques used in RF transmission Power vacuum devices: The principles and applications of gridded vacuum tubes and microwave power devices Solid-state power devices: The operating parameters of semiconductor-based power devices RF components and transmission lines: The operation of hardware used to combine and conduct RF power Antenna systems: The different types of antennas and their basic operating parameters Troubleshooting: Basic troubleshooting techniques and the operation of important test instruments Contrary to the perceptions of many, RF technology remains a dynamic field that continues to advance to higher power levels and higher frequencies. Those who specify, install, and maintain RF equipment will welcome this reference that uniquely serves their needs.

This book describes the principles and applications of radiofrequency treatments for various spinal indications, including disc herniation, discogenic and radicular pain, facet joint arthropathy, and benign and malignant lesions of the vertebral column. The aim is to provide a handy guide that will acquaint readers with all aspects of radiofrequency neurotomy at different levels of the spine, enabling them to carry out treatments effectively and safely. Radiofrequency neurotomy, or radiofrequency ablation, is a minimally invasive procedure that is associated with a reduction in complications, side effects, and risks of anesthesia as well as with lower costs. This book, written by world-renowned authorities in the field, fills a significant gap in the literature by specifically focusing on the use of radiofrequency for spinal conditions. It will be of value to a range of specialists, including interventional neuroradiologists and radiologists, neurosurgeons, and orthopedists.

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.
