# Numerical and Experimental Studies on Frequency Characteristics of $\hbox{TE}_{11}$-Mode Enhanced Coaxial Vircator

#### Abstract

Due to azimuthal-asymmetric electron emitting, TE11 -mode output of high-power microwave is unavoidable in coaxial vircator. In order to obtain a pure mode output, TE11-mode enhanced design by opposed section electron emitting is applied. As 2-D effect along azimuthal direction is introduced, the frequency of microwave generated is shifted in TE11-mode… (More)
