NONUNIFORM TRANSMISSION LINES AND BROADBAND MICROWAVE ABSORBERS

Abstract

Theoretical absorbers are proposed whose performance should be better than that of the commercial absorbers presently available. Some measurements and considerations on commercial absorbers are appended as a confirmation of the fact that, when the measurements are properly interpreted, their performance is considerably inferior to that of the proposed theoretical absorbers. The performance of the commercial absorbers is ordinarily measured on panels of limited dimensions and under slightly oblique incidence. However, as the reradiation patterns of a metal plate covered with an absorbing layer are considerably broader than those without absorber, the data obtained by this method are generally far better than those obtainable by waveguide measurements or theoretical evaluation and valid for normal incidence.
