Reflective properties of electromagnet-optical waves in superconducting plasmas

Summary form only given, as follows. Superconducting (SC) plasmas were discovered recently, the studies of which are becoming important. As for the SC plasmas, the penetration depth of magnetic fields to the superconductor due to the fundamental Meissner effect is given by /spl lambda/=c//spl omega//sub PS/, (/spl omega//sub PS/: the SC electron plasma frequency). The investigations on the SC plasmas are progressed in this report. Especially, electromagnetic-optical field distributions near the SC plasma boundary are numerically investigated, when electromagnetic-optical beam waves with finite size are radiated to SC plasmas with ambient incident angle. Typical electric field patterns for the TE incident wave are shown. The figure indicates the existence of the parallel shift of the reflective position of the beam wave for the case of the perfect reflection. The reflective shift is found to result from field penetrations to the superconductor which depend on the parameters of the SC plasmas.
