A single-period TE/sub 02/-TE/sub 01/ mode converter in a highly overmoded circular waveguide

A single-period 60 GHz TE/sub 02/-TE/sub 01/ mode converter for use in an electron cyclotron heating (ECH) system for magnetically confined plasmas is presented. The mode converter is very compact and has a broad bandwidth and a theoretical conversion efficiency of 97.6%. A method of computing the reflection from converters is presented and used to show that reflection from the single-period mode converter is minimal. Experimental results are consistent with theoretical calculations.<
