EFFECTS OF ENVIRONMENTS ON THE SURFACE WAVE CHARACTERISTICS OF A DIELECTRIC-COATED CONDUCTOR-PART III

Abstract

The sarface wave characteristies of a circular cylindrical conductor coated with stratified dielectrics have been theoretically studied. Six diffrent profiles E (p) of dielectric constant in the p -direction, viz., square, fourth power, exponential etc.have been considered. The results of analysis indicate greater concentration of surface wave _field within the dielectric media when the conductor is coated with two concentric radially stratified dielectrics satisfying square-law and fourth power-law profiles. The at constant is also less contpared with that of a conductor coated with hontogeneous dielectrics.
