PULSE REFLECTION FROM A LOSSY LORENTZ MEDIUM HALF-SPACE (TM POLARIZATION)

A closed form solution for transient reflection from a lossy Lorentz medium half-space has been expressed as an infinite series of Bessel functions of the first kind and fractional order. The delta pulse plane wave excitation in the case of TM polarization has been considered. The variation of a reflected waveform with the angle of incidence, normalized collision frequency and normalized characteristic binding frequency of a lossy Lorentz medium are presented in several computer plots. The time domain Brewster angle is noted in the early time response. It is shown how the obtained transient response might be used for diagnosing the main characteristic parameters of the Lorentz medium.
