摘要：
Interactions between 2-D cavities embedded in a ground plane are investigated using a numerical model. The problem is first discretized in time using the Newmark method, and 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, crosstalk between cavities of different depths and at different distances is investigated. Influence of additional cavities on aperture fields is shown to decrease exponentially as a function of separation between cavities.
