Surface TM wave propagating at the boundary of isotropic collisionless plasma moving at a relativistic velocity

Abstract

The dispersion properties of a surface TM wave propagating at the boundary of isotropic collision-less plasma moving at a relativistic velocity are described. The phenomenon of aberration, whereby the wave normal of the surface wave deviates from the boundary plane and rotates in the direction of motion, takes place only in the laboratory frame. The subrelativistic motion of the plasma is manifested by a decrease in the cutoff frequency of the surface TM wave and by the appearance of a long-wavelength limit in the TM wave spectrum, which shifts toward shorter wavelengths with increasing plasma velocity, thus reflecting the indissoluble unity of space and time.
