Abstract

The issue of waveport modeling for the numerical simulation of electromagnetic devices using the discontinuous Galerkin time-domain (DGTD) method is investigated. A new implementation of the waveport boundary condition (WPBC) is presented along with a fast evaluation of the required convolution. The performance of the WPBC for the DGTD simulation is then compared with that of the first-order absorbing boundary condition and the uniaxial perfectly matched layer (UPML). Two numerical examples are presented to demonstrate the waveport modeling for the DGTD simulation of electromagnetic devices based on the WPBC and UPML.
