Abstract

In this paper, a new absorbing boundary condition based on the advection equation has been proposed, which considers the attenuation of electromagnetic waves propagating towards the absorbing boundaries. The validity of the proposed condition has been tested by comparing the results, calculated using the FDTD method with the proposed absorbing boundary condition, with those calculated with other representative absorbing boundary conditions such as Liao's first- and second-order conditions. It has become clear that the proposed absorbing boundary condition is more effective than the other representative advection-equation-based absorbing boundary conditions.
