Counterposed phase velocity and energy-transport velocity vectors in a dielectric-magnetic uniaxial medium
Abstract:When a plane wave is launched from a plane surface in a linear, homogenous, dielectric–magnetic, uniaxial medium, we show that its phase velocity and the energy–transport velocity vectors can be counterposed (i.e., lie on different sides of the surface normal) under certain circumstances.
