Tunable Three-Dimensional Photonic Crystal Microwave Resonator with Ultra-Small Mode Volume
Microwave resonator is an important electromagnetic tool with applications in many areas, including communication, nonlinear optics, cavity quantum electrodynamics, and precision metrology. In this work, we did simulations and experiments on a design of three-dimensional (3D) dielectric photonic …

Optimization of a microwave resonator cavity to perform electron spin resonance measurements on quantum dots
… magnetic field at temperatures around 100mK. A resonator cavity is used to expose the quantum dot to a perturbational microwave magnetic field pulse that induces electron spin flip transitions. The statistics for measuring the probabilities of these transitions can be improved by increasing the …

Microstrip Superconducting Quantum Interference Devices for Quantum Information Science
<p>Quantum-limited amplification in the microwave frequency range is of both practical and fundamental importance. The weak signals corresponding to single microwave photons require substantial amplification to resolve. When probing quantum excitations of the electromagnetic field, the substantial …

DETERMINING THE QUALITY OF PASTEURISED AND HOMOGENISED COW MILK USING MICROWAVE SENSORS
… research work is to design and develop a novel, microwave spectroscopy, approach for determination of overall quality of milk. In particular, this quality determination of milk products was achieved by identification of deterioration or spoilage of milk over time, classification of the milk …

Untersuchung von Photonenzahlzustaenden mit dem Ein-Atom-Maser
… photon number states of an extremely long lived resonator field are described. Three different methods are discussed, all of them using the one-atom-maser apparatus, which examines the interaction of single atoms of a weak thermal atomic beam with a single mode of a microwave resonator with a …
