An ac method for the precise measurement of Q-factor and resonance frequency of a microwave cavity
TL;DR: In this article, a new and fast method for the determination of the complex frequency shift of a microwave resonant cavity was developed based on frequency modulation of the microwave source around the cavity resonance and detection of the 2nd and 4th harmonic of the modulation frequency.

Flux-pinning effects in field-modulated microwave absorption of YBa2Cu3O7−δ thin films
TL;DR: In this paper, the shape of the field-modulated microwave-absorption signal in the mixed state of type-II superconductors reveals the field dependence of the fluxpinning parameters.

Comparative investigation of intrinsic Josephson contacts in HTC superconductors by modulated microwave absorption measurements
TL;DR: In this article, a quantitative analysis of the temperature dependence of modulated microwave absorption measurements in a sputtered film, a single crystal and a ceramic sample reveals two different types of intrinsic Josephson contacts.

Critical fluctuations and pseudogap observed in the microwave conductivity of Bi2Sr2CaCu2O8+delta, Bi2Sr2Ca2Cu3O10+delta, and YBa2Cu3O7-delta thin films
TL;DR: In this paper, a consistent analysis of the real and imaginary parts of the fluctuation conductivity can be achieved only if an appropriate wave vector or energy cutoff in fluctuation spectrum is taken into account.
Short-wavelength cutoff effects in the ac fluctuation conductivity of superconductors
TL;DR: In this paper, the short-wavelength cutoff has been introduced in the calculation of the ac fluctuation conductivity of superconductors, and it is shown that a finite cutoff leads to a breakdown of the scaling property in frequency and temperature.
