“…As one might expect in a high power region the dependence of ∆R/R on P deviates from the linear dependence predicted by (1). It is well established that dependence of ∆R/R on the pulse power in a wide range of P can be approximated by the second order polynomial [2] with two parameters that are determined from the fitting procedure. Two term approximations are shown in Fig.…”

An experimental investigation of a high power millimetre wave pulse sensor is presented. Two groups of sensors with a flat frequency response were fabricated according to results of the optimisation. The frequency response and voltage standing wave ratio were measured and compared with results of the electrodynamical simulations. The largest measured sensitivity variation of the best sensors within waveguide frequency range was ±8%. The reasonable agreement between measured and simulated values of the sensitivity was obtained.

“…One of the possible solutions might be a resistive sensor (RS) the performance of which is based on the electron heating effect in n-Si. The waveguide type RS shows itself as an attractive device for HPM pulse measurement in a centimeter wave region [3]. It measures HPM pulses directly, it is resistant to large power overloads and demonstrates a very good long-term stability.…”

We report on the numerical investigation of the resistive sensor for the 78-118 GHz range. A three-dimensional finite-difference time-domain method was applied to simulate the wave propagation within a waveguide segment with the semiconductor sensor attached to a wider wall of the wave--guide. The electric field distribution, voltage standing-wave ratio and the average electric field dependences on frequency have been determined for several sets of dimensions and specific resistances of the sample. It is demonstrated that a proper selection of the dimensions and specific resistance of the sample can compensate the waveguide dispersion and the decrease of the electron heating effect with frequency. Therefore, a nearly constant sensitivity of the sensor can be obtained for the entire frequency range.

“…A resistive sensor (RS) is one of the promising devices for HPM pulse applications, when the fast response, stability and resistibility to overload and breakdown are of the most importance [1]. Several types of the RS for different HPM pulse power level and duration were developed.…”

Two types of resistive sensors with flat frequency response for microwave pulse power measurements in X-band rectangular waveguide WR-90 up to 100 kW were developed and experimentally investigated. The first type of the sensors demonstrates higher sensitivity and larger output signal, while the second one exhibits better linearity of the output signal. The experimental investigations revealed the sensitivity variation within ±10% in 8.2-12.2 GHz frequency band.
