Transient Response Of A Wedge With Two-face Impedances: A Uniform Time-donfafn GTD Solution And Applications

Abstract

The problem of transient electromagnetic scattering from a plane wedge with arbitrary impedances on the two faces is addressed in this presentation. Analytical formulations have been developed for the transient response of the wedge based on the time-domain version of the frequency domain diffraction coefficient for the wedge with two face impedances originally presented by Tiberio and his coworkers (1985). The bistatic fields due to such an impedance weldge have been plotted for arbitrary wedge angles, polarizations and surface impedances. The special case of time domain scattering of the impedance half plane, impedance full plane and an impedance right-angled wedge have also been treated. The analysis has been applied in a practical example of time domain scattering from a two-face impedance and a coated plate.
