Abstract :
The computer-aided design of a dual-depth E-plane corrugated waveguide polariser is described which achieves 90±1° differential phase shift between the TE10¿ and TE01¿ wave transmission coefficient for 11.2¿14.8 GHz. The method of field expansion into suitable eigenmodes used considers the effect of higher-order-mode interaction at the step discontinuities.
