Evanescent Mode Technique—Theory and Application

Abstract

The theory of evanescent mode guide is explained. An equivalent circuit in π-configuration and an inverter in cut-off technique are derived. The elements of the equivalent circuit are given in terms of line constants and the practical values are calculated. Advantages and potential applications of this technique to realize high quality microwave components for FM and PCM communication systems are discussed.
