Monograph, ČVUT, Prague, 2005, pg.192The textbook builds on basic knowledge of time varying electromagnetic fields gained from courses in physics and electromagnetic field theory. The textbook introduces all the basic knowledge that an electrical engineer specializing in radio engineering and telecommunications should have and that is necessary for further courses such as microwave engineering, antennas and propagation, optical communications, etc.
The course in Waves and Transmission Lines studies the theory and applications of classical electrodynamics. It is based on Maxwell’s equations. This course provides a basis for understanding the behavior of all high frequency electric circuits and transmission lines, starting from those applied to transmitting and receiving electric energy, processing signals, microwave circuits, optical fibers, and antennas. The main applications lie in wireless communications, radio engineering and optical systems.
Transmission lines are designed to transmit guided waves. After introducing the general properties of guided waves the TEM wave is treated, and the transformation of impedances along a line is described. The Smith chart, a very effective graphical tool for analysis and design of high frequency circuits, is described and its basic applications are explained through particular problems. Waves propagating along waveguides with metallic walls of rectangular and circular cross-sections are studied. Dielectric waveguides are treated separately. They form the basis of optical fibers. Cavity resonators, unlike low frequency L-C resonant circuits, are able to resonate on an infinite row of resonant frequencies.CONTENTS:
