INVESTIGATIONS ON ARTIFICIAL DIELECTRICS AT MICROWAVE FREQUENCIES Part II

Abstract

The expression for the phase change on transmission of an electromagnetic wave incident on a parallel plate type artificial electric, as a function of the plate spacing has been verified experimentally. The theoretical and experimental results agree fairly well for ratios of plate spacing to wavelength from 0.5 to 0.85. On the basis of a theory due to Woonton, the "Fresnel type of diffraction for an artificial dielectric with ratio of plate spacing to wavelength of 0.64 has been theoretically investigated. There is close agreement between experimental and theoretical results.
