Emphasizing the use of electromagnetic theory to explain basic concepts, this reference provides procedures for producing designs of microwave devices which satisfy specified performance criteria. The book provides coverage of an initial exposure to microwave components that use active elements such as solid state diodes and transistors; rectilinear wave-guiding structures, with emphasis on coaxial lines, stripline, microstrip, rectangular and cylindrical waveguide, and various slow-wave configurations; pro pagating modes distinguished by fields that are totally transverse (TEM), have a transverse E field (TE), or have a transverse H field (TM); mode voltage, current, and impedance; the reflections caused by arbitrary terminations and remedies for their suppression; a technique for calculating dielectric and ohmic losses; passive, linear microwave devices; the theory and design of transformers, resonators, power dividers and hybrid junctions, directional couplers, and filter; and more. Suitable for specialists in electromagnetic theory.
