Query: Oblique surface Josephson plasma waves in layered superconductors   We have theoretically studied oblique surface waves (OSWs) which propagate
along the interface between a dielectric and a layered superconductor. We
assume that this interface is perpendicular to the superconducting layers, and
OSWs at the interface can propagate at an arbitrary angle with respect to them.
The electromagnetic field of the OSWs in a layered superconductor is a
superposition of an ordinary wave (with its electric field parallel to the
layers) and an extraordinary wave (with its magnetic field parallel to the
layers). We have derived the dispersion equation for the OSWs and shown that
the dispersion curves have end-points where the extraordinary mode transforms
from evanescent wave to bulk wave, propagating deep into the superconductor. In
addition, we have analytically solved the problem of the resonance excitation
of the OSWs by the attenuated-total-reflection method using an additional
dielectric prism. Due to the strong current anisotropy in the boundary of the
superconductor, the excitation of the OSWs is accompanied by an additional
important phenomenon: the electromagnetic field component with the orthogonal
polarization appears in the wave reflected from the bottom of the prism. We
show that, for definite optimal combinations of the problem parameters (the
wave frequency, the direction of the incident wave vector, the thickness of the
gap between dielectric prism and superconductor, etc.), there is a complete
suppression of the reflected wave with its polarization coinciding with the
polarization of the incident wave. Contrary to the isotropic case, this
phenomenon can be observed even in the dissipationless limit. In such a regime,
the complete transformation of the incident wave into a reflected wave with
orthogonal polarization can be observed.
