The Terminal Responses of the Two-Wire Line in Multiaperture Cavities Based on Electromagnetic Topology and Method of Moments

الملخص EN

A simulation technique based on electromagnetic topology (EMT) theory is proposed for analyzing electromagnetic interference (EMI) coupling through apertures onto the two-transmission line enclosed within metallic structures.

The electromagnetic interactions between apertures and the external-internal interactions were treated through the topological decomposition and the multistep iterative method.

Then, the load responses of the two-wire transmission line are resolved by the the Baum-Liu-Tesche (BLT) equation.

The simulation results both without and with the electromagnetic interaction are presented for the frequency range from 100 MHz to 3 GHz.

These numerical results obtained by two methods imply that the electromagnetic interaction cannot be simply ignored, especially for the frequency range up to 1 GHz.
