Abstract :
An equivalence-principle-based model for predicting the radiation from TE/sub 0n/ and TM/sub 0n/ mode step-cut and slant-cut Vlasov feeds is discussed. Theoretical far-field and numerical near-field radiation patterns are compared to measured results. Experimental investigations of currents are reported, and simulation of perturbed waveguide currents is explored.<>
