Theoretical and Experimental Investigations on a 90° Compact TM₀₁-TE₁₁ Mode Converter for RBWO

Theoretical and experimental investigations on a compact TE11 mode bend for high‐power transmission line

“…As one of the key components in the HPM application system, the oversized 90 °cir. TE 11 bend is often necessary to make the transmission direction of electromagnetic wave to turn 90 °in the transmission line, and it is usually applied together with a mode converter, such as the cir.TM 01 -cir.TE 11 converter [13][14][15][16][17]. For example, a 90 °cir.TE 11 -cir.TM 01 converter with inserted metal plates is designed in ref.…”

“…TM 01 ‐cir.TE 11 converter and cir.TE 11 bend together, and designed a 90 ° cir.TM 01 ‐cir.TE 11 converter with hollow waveguide in ref. [17]. It successfully achieves a high power handling capacity, and the TE 11 mode's polarisation direction is also parallel to the waveguide's bending plane.…”
