Abstract :
The electromagnetic modeling of distributed or other highly complex systems requires reliable and strongly adaptable simulation algorithms. In this respect, the finite-volume time-domain (FVTD) method is a promising and very flexible approach in the class of volume-discretizing numerical techniques, because of its combination of explicit time stepping with an unstructured, inhomogeneous mesh. For scattering problems, in order to achieve accurate simulation results, a highly absorbing boundary truncation scheme is required. This paper proposes an approximate conformal perfectly matched absorber for the FVTD method and demonstrates its applicability with a practical example of the simulation of mutual coupling between two dielectric resonator antennas (DRAs).
