Transmittance of electromagnetic waves through finite-length layered superconductors in presence of external static magnetic field

Abstract

We study the transmission of electromagnetic waves in the presence of external DC magnetic field through a sample of layered superconductor of finite thickness. We show that the external DC magnetic field can be a useful tool to adjust the transmittance of the sample and to vary it over a wide range. Moreover, the right choice of the external DC field provides the total transparency of the sample for the wide range of frequencies.
