Abstract
In this paper, we validate the aforementioned technique as a means for lattice truncation of different types of media. It is shown through two numerical examples that the method is applicable to both conductive and dispersive media, presenting numerical errors comparable to those of PMLs. Also, it maintains stable performance in cases where conventional absorbers fail to function satisfactorily.
