“…Anyway, there is no rigorous theoretical model to describe the features of the nonlinear HTSC-based transmission line. The well-known phenomenological model for the propagation of a microwave signal through the transmission line [8][9][10] does not take the presence of the dc component into account. Therefore, in this work, in order to quantitatively describe the observed effect, a task was formulated to generalize the known phenomenological model onto the case of power supply to the microwave transmission line by a direct current.…”

A phenomenological model has been proposed to describe the avalanche-like transition of a microwave nonlinear HTSC-based transmission line into a dissipative state. This effect was observed by the authors in a dc-biased transmission line. The proposed model generalizes the well-known phenomenological model for the nonlinear HTSC-based transmission line under the action of a direct current. The character of the dependences obtained for microwave losses allows the jump-like changes in the properties of the nonlinear HTSC-based transmission line to be regarded as a fold-type catastrophe and the methodological and mathematical apparatus of the theory of catastrophes to be used in order to explain the results obtained and predict new ones.

“…7, b. Because of highly nonlinear dependence of the quality factor of YBCO resonators on the supplied microwave power [10][11][12], the measurements were carried out at the minimum power P out = −37 dBm, at which it was possible to extract the resonance peaks from the noise. For both resonators operating on the first mode, the quality factor was greater than 11000 that is about 280 times greater than the calculated quality factor for the copper analogues.…”

Numerical calculations of the characteristics of the meander-and fractalshape (Hilbert curve) topologies of close-packed microstrip resonators are performed. The amplitude-frequency characteristics, resonance frequencies, quality factors, and geometric factors are calculated. The mechanisms of neighbouring resonator segments' interaction are found. The latter strongly affects both the resonance frequency and the quality factor. Two hightemperature superconducting fractal-shaped microstrip resonators are fabricated using thin films of YBa 2 Cu 3 O 7−δ (YBCO); the amplitude-frequency characteristics, the resonance frequencies, and the quality factor-frequency dependences are measured. Frequency dependence of a surface resistance of the YBCO film is found. The quality factors of the superconducting and copper resonators are compared, and the reasonability of the YBCO films' usage as a material for thin-film resonators' manufacturing is assessed.
