Wave reflections from a conducting surface with a moving uniaxial sheath

The behavior of a plane wave incident from an isotropic medium onto a perfectly conducting plane covered with a moving uniaxial sheath is studied in detail. The governing equations are formulated by making use of the transformed constitutive relations of the moving sheath viewed as a stationary bianisotropic medium. The dispersion equations for the ordinary and extraordinary components of the wavenumber in the moving sheath are then obtained. Complete field expressions for both the reflected wave and the wave in the moving medium are given in terms of the longitudinal field components of the incident wave for an arbitrary orientation of the plane of incidence and an arbitrary angle of incidence. Several special cases are considered and some interesting numerical results are presented in graphical form.
