Abstract

In this paper, we consider the time-domain scattering problem of a two-dimensional overfilled cavity embedded in an impedance ground plane. An artificial boundary condition is introduced on a semicircle enclosing the cavity that couples the fields from the infinite exterior domain to those fields inside. The problem is first discretized in time using the Newmark scheme, and at each time step, we derive the variational formulation for the TM polarization, and establish well-posedness. Numerical implementation of the method for both the planar and overfilled cavity models is also presented.
