The most remarkable feature ofthese microwave devices is that the high-frequency surface resistance ofsuperconducting films is smaller than that of metal thin films. The size of themicrowave devices is dictated by wavelength and the thin films are generally requiredto be not smaller than a few square centimeters. Though pulsed laser deposition展开更多
