Impulse reflection with arbitrary angle of incidence and polarization from isotropic plasma slabs

摘要

The nature of the reflected signal is considered for an electromagnetic impulse impinging on a semi-infinite plasma and a finite plasma slab terminated by a perfectly conducting surface at arbitrary angles of incidence and for both polarizations. The inverse Fourier transform technique is used and leads to a statement for the reflected signal in terms of Bessel functions of the first kind. The results are shown graphically for both the TE and TM case for all angles of incidence between normal and π/2.
