PROPAGATION OF MICROWAVES THROUGH A CYLINDERICAL METALLIC GUIDES FILLED COAXIALLY WITH TWO DIFFERENT DIELECTRICS - PART V

Abstract

The general conditional equation from which the propagation constant of the hybrid mode can be derived has been formulated by utilising the field components and boundary conditions given in a previous paper (Chatterjee, 1954).The propagation characteristics have been calculated in the case when the cylindrical guide containing two coaxial dielectrics is reduced to a simple dielectric rod. The dielectric rod behaves as a guide or as an aerial depending on a certain limiting value of the radius of the rod. The critical value of the radius depends on the mode in which the rod is excited.
