THE TRANSVERSE MAGNETIC-WAVE AND THE BREWSTER-ANGLE FOR A DIELECTRIC MEDIUM MOVING IN AN ARBITRARY DIRECTION

The reflection and transmission of a transverse magnetic wave, and in particular the Brewster angle, are investigated for the case of a diel ectric medium moving in an arbitrary direction. Various interesting fe atures concerning the variation in the field vectors, the reflection a nd transmission coefficients, and the Brewster angle, are discussed as functions of the velocity and the refractive index of the moving medi um. Specifically, the condition of obtaining amplitude amplification a ccompanied by frequency multiplication, the polarization of the field vectors in both the reflected and the transmitted waves, the wave feat ures of the reflected wave under the Brewster angle, and the physical effects which occur in the case where the medium moves in an arbitrary direction but do not occur in the case where the medium just moves in some particular directions are discussed in detail.
