Analysis and Design of TM01 and TE01 High-Power Handling Corrugated Flexible Waveguides

The purpose of this article is to solve the issue that current high-power microwave (HPM) transmission links are used in the rigid metal waveguide, which causes significant installation difficulties to the system integration. In this article, we design the TM01 and TE01 high-power handling corrugated flexible waveguides using a numerical analysis method based on coupled wave theory. The measured results are in good agreement with the numerical calculation method. The designed TM01 corrugated flexible waveguide has a transmission efficiency of up to 98% at bending angles less than ±5°, and correspondingly, the TE01 corrugated flexible waveguide has a transmission efficiency of up to 98% at bending angles less than ±8°. The designed flexible waveguides are all capable of power capacities of more than 3 GW.
