The results of the spectral analysis of a high-temperature superconducting (HTSC) log-periodic antenna integrated with a HTSC Josephson junction (JJ) and operating, in this case, as a test resonant system are presented. Current-voltage characteristic

Here we report the results of terahertz photonic elements frequency analysis by the ac Josephson effect. We considered planar resonators. There were observed excitation of fundamental and dipole resonance modes in photonic elements by Josephson oscil

We developed a self-consistent method for the calculation of spatial current distributions in high-Tc grain-boundary junctions. It is found that crystallographic anisotropy of high-Tc superconducting electrodes results in the effects, which previousl

Specific values of characteristic voltages IcRn and normal-state resistances Rn of high- Tc Josephson junctions (JJ) are often required for their THz applications in detection and spectroscopy. Recently, evolution of these electrical parameters of [0

We have fabricated and characterised superconducting tunnel junctions with annular geometry for radiat ion detection. The advantage of the annular geometry is that, once the trapping has occurred the magnetic field can be switched off and there is no

Application of Josephson admittance spectroscopy for the spectral analysis of a broad-band log-periodic antenna was demonstrated at the frequency range from 50 to 700 GHz. A real part of the antenna admittance was reconstructed as a function of the f

Detection of terahertz radiation using YBa2Cu3O7-x [100]-tilt bicrystal junctions with high IcRn- product up to 6 mV has been studied. Two types of the responses ΔV (V) have been observed. At low frequencies up to some frequency fl, the responses Δ

A comparative analysis of the magnetic flux trapping in monocrystalline and polycrystalline HTSC samples is carried out, and the possibility of employing the dependence of the trapped magnetic flux on the external magnetic field for obtaining compara
