Recent advances in HPM pulse measurement using resistive sensors

The resistive sensor (RS), whose performance is based on the electron heating effect in semiconductors, has found application in high-power microwave (HPM) measurements. Our previous studies concentrating on the waveguide-type RS have demonstrated their advantages over conventional diodes that are also used to measure HPM pulses M.Dagys et al. (2001). The RS can detect about 60 dB greater power level, are resistant to large power overloads and demonstrate very good long-term stability. They can produce an output signal on the order of a few tens of volts without any amplification circuit and can resolve nanosecond duration HPM pulses. In this paper we present a brief overview of the waveguide-type RS as well as a survey of recent advances in the RS design.
