Abstract:

In this thesis I describe work on developing theoretical and numerical models of supercon- ducting thin-film microwave resonators. Superconducting resonators are used in a variety of applications, one of which is as kinetic inductance detectors (KIDs). KIDs are ultra-low noise, highly sensitive, multiplexable detectors, with uses in a wide variety of fields including astrophysics, medical imaging, and particle physics. Resonators are also crucial for supercon- ducting qubit readout, superconducting mixers and parametric amplifiers, and as multiplexers for other devices. The results described i

Abstract:

The Cold-Electron Bolometer (CEB) is a sensitive detector of millimeter-wave radiation, in which tunnel junctions are used as temperature sensors of a nanoscale normal metal strip absorber. The absorber is fed by an antenna via two Superconductor-Insulator-Normal metal (SIN) tunnel junctions, fabricated at both ends of the absorber. Incoming photons excite electrons, heating the whole electron system. The incoming RF power is determined by measuring the tunneling current through the SIN junctions. Since electrons at highest energy levels escape the absorber through the tunnel junctions, it cau

This thesis presents the development of kinetic inductance detectors (KIDs) for cosmic microwave background (CMB) polarimetry. Increasingly precise measurements of the CMB have led to much of our understanding of the observable universe; future measurements of the CMB will require the development of new detectors as progressively fainter signals are targeted. In particular, a measurement of the primordial B-mode polarization signal, which would offer strong evidence of inflation, will require at least a 50 times increase in detector count. KIDs are an attractive detector option for next-genera

Shottky diodes are commonly used for microwave detection. Because it is a majority carrier component, and that the point contact plane is smaller for higher switching speed, as compared with p-n junction diodes. However, the junction capacitance of same economic bipolar junction transistors which applied in microwave frequency is small enough to perform fast switching. Thus it can be need to replace Shottky diode to

Abstract:

碩士<br>國立中正大學<br>電機工程所<br>98<br>In this thesis, passive microwave power detectors with zero power consumption were developed based on the rectenna technique. The first passive power detector detects 2.45 GHz microwave power emitted in the wireless environment. The conversion efficiency is 29.4% at the input power of 7 dBm. The circuit was realized on FR4 substrate with the size of 17.9 mm×9.3 mm. To further enhance the conversion efficiency, a tunable matching circuit was designed in front of the microwave rectifying circuit. Because the internal impedance of the microwave rectifying circuit va
