## Abstract Gaussian beam‐mode expansion with only the fundamental mode does not work properly when the angular region of interest is wide. It is necessary to use higher‐order mode for the expansion. A study of the convergence of these higher order modes is presented for the case of a corrugated co
## Abstract Some numerical results for a conical horn with three modifications of a hard corrugated PBG wall are presented. It is shown that a completely corrugated horn of diameter 4–5 wavelengths provides 80–87% aperture efficiency and a cross‐polar level below −30 dB for a horn length greater th
