Recent advances in high-temperature superconductors (HTS) have made them extremely attractive for low-temperature, high-magnetic-field-power applications such as in fusion technology, where the advantages over traditional low-temperature superconduct

We present numerical and experimental results aimed at reducing the uncertainties in measurements of the quality factor and resonance frequency of microwave resonators. We focus on the optimization of the frequency span and on the role of uncalibrate

We present the multifrequency measurements of the surface resistance of spark-plasma-sintered MgB2 performed through a dielectric loaded resonator operating at 16.5 and 26.7 GHz. By normally applying magnetic fields ≤1.2 T to the sample surface, we

The root mean square surface roughness Rq of metals is detrimental in several microwave applications. Rq characterization methods are thus largely used and of great interest. In this work, a new dielectric loaded resonator (DR) design is proposed to

Axions, hypothetical particles theorised to solve the strong CP problem, are presently being considered as strong candidates for cold dark matter constituents. The signal power of resonant-based axion detectors, known as haloscopes, is directly propo

A new configuration of dielectric loaded resonator, particularly versatile for the complex permittivity measurement of substrates for microwave circuits, even in presence of back metal plates, is here shown. In order to test this technique in a wide
