mode converter for Gyroklystron is obtained to realize optimal mode conversion by a code written based on the mode coupling theory
and a 30.5GHz TE
11
-HE
11
mode converter is designed by High Frequency Structure Simulator (HFSS).Results show that complex TE
11
-HE
11
mode converter consisting of the two converters has a transforming efficiency of over 97% within bandwidth of 1% at frequency 30.5GHz.Test indicates that the complex mode converter acts very well in conversion of TE
