摘要

An efficient analytical model based on electromagnetic topology (EMT) has been developed for predicting the electromagnetic (EM) field coupling to a rectangular enclosure with an electrically large aperture via a penetrated transmission line (TL), excited by an external plane wave of oblique incidence. First, the electric field in the enclosure is calculated based on the modified Bethe's small holes theory and mirror procedure. Then, the topology networks of the EM interaction are constructed by analyzing the coupling paths and mechanism, and the electric current induced at the termination loads of the TL is obtained using the generalized Baum-Liu-Tesche equation combined with the Agrawal's model. The analytical model has been successfully verified by the finite difference time domain method over a wide frequency band of 0.5 similar to 3GHz, which consumes less time than numerical methods. Finally, the analytical model is employed to analyze the effect of various parameters on the induced current, including the length, the height, and the direction of the line.
