Finite-Element Boundary Integral Simulation of Transient Electromagnetic Scattering from Multiple Cavities

Finite-Element Boundary Integral Simulation of Transient Electromagnetic Scattering from Multiple Cavities

Capt. Richard Uber and Aihua Wood

Abstract:

In this work, interactions between two-dimensional cavities embedded in a ground plane are investigated using a numerical model. The problem is first discretized in time using the Newmark method, then a variational formulation is used for numerical implementation. Numerical experiments are conducted for one, two, and three cavity environments considering both continuous and Gaussian incident fields. Finally, cross-talk between cavities of different depths and at different distances is examined. Influence of additional cavities on aperture fields is shown to decrease exponentially as a function of separation between cavities
