Abstract :
This work proposes a phenomenological approach to description of radiofrequency (rf) response (RRSMI) of high-temperature superconductors (HTS) to microwave (mw), including millimeter-wave, irradiation. The YBaCuO films and ceramic RRSMI was studied by means of quasioptical dielectric resonator (QDR) of Al2O3 single crystal for application of radiation (at about 34.9 GHz) and probe mw signal (at 37.6 GHz) and inductance coil included in a rf resonance circuit for the response measuring at a frequency of 9 MHz. QDR with HTS samples was excited with mw signal from the pump generator with output power to 5W in 8 mm wave band
