SURFACE WAVE CHARACTERISTICS OF A CYLINDRICAL METALLIC CORRUGATED STRUCTURE EXCITED IN Eo - MODE

Abstract

The investigations are concerned with a systematic study of the electromagnetic surface wave characteristics of the electromagnetic surface wave characteristies of a eylindrical metallhc conductor corrugated uniformly and excited in Eo -mode The invesiigarions include
(i) Deterrnmation of the parameters of the structure for which it can
support a surfore wave.
(ii ) Study of the differnt properties of the surface wave such as
(a) Guide wove length
(b) Power flow
(c) Dispersion characteristics
(d) attenuation
and their variation with structure parameters.
(iil) Study of the effect of higher order space harmonics on the propagation
characteristics of the structure.
