Study of the Possibility to Switch the TE01 Mode of a Circular Waveguide Using the Multipactor Discharge in Crossed Fields

Abstract

We demonstrate experimentally that it is possible to control the symmetric TE01 mode of a circular waveguide, whose microwave electric field is equal to zero at the wall), using the multipactor discharge in the crossed electric and magnetic fields, which is excited by the TM01 mode in a cylindrical cavity. The characteristic time of cavity switching is determined by the cavity Q-factor and is equal to 150–200 ns. The experiments show that the proposed scheme allows reflecting the energy flow of switched radiation almost completely.
