Abstract:
Device for protection against high power microwave radiation was created based on a pair of noninteracting microstrip resonators, which are coupled in the working frequency band via a third resonator based on a thin film of high temperature superconductor (HTS). Under the action of a MW radiation with the power above a certain threshold, the HTS film element transits to normal state. This leads to the fall in the coupling between input and output resonators, and, as a sequence, to the power limitation at the device output due to a strong signal reflection from the input.
