The interaction of a semiconductor plate with TE01 (H01) wave in a circular waveguide has been investigated. A plate with contacts on its top and bottom serves as a sensing element (SE) for a resistive sensor (RS) based on the electron heating effect and devoted to high-power microwave pulse measurement. A three-dimensional finite-difference time-domain method was applied to simulate wave propagation...
A high power millimetre wave pulse sensor for 78-118 GHz frequency range has been developed. A finite difference time domain method was applied to optimise the sensor's frequency response. Two groups of sensors were manufactured and tested experimentally. A voltage standing wave ratio and dependence of the output signal on pulsed power have been measured. The sensor has been tested up to 2 kW pulse...
