Abstract:
Lower- and upper-bound expressions were obtained for the susceptance of a circular obstacle excited by the TE sub01 mode in a circular wave guide. The solutions were obtained by a variational method. Experiments showed the TE sub01 mode to be about 60 db above extraneous modes over a free-space, wave-length range of 7.30 to 11.90 cm. The discrepancies between theoretical and experimental results are attributed to finite thickness and conductivity of the obstacle, ellipticity of the circular wave guide, presence of lower-order propagating modes, and typical errors involved in the measurement of admittance by the resonance-curve method.
