We present a new face centered approach to the collocation of the fields for the application of a surface impedance boundary condition (SIBC). This approach deals with the ambiguities in the surface normal that arise at the edges on stair-cased surfaces.. The accuracy of the new scheme is compared to edge based and conformal approaches using both planar sheet and spherical shell test cases. Stair-casing...
In this work, we present a novel hybrid implicit-explicit algorithm, based on a subgridding boundary condition (SGBC) technique, for the simulation of arbitrarily dispersive thin layers in FDTD. To overcome a reduction of the usual FDTD time step, a Crank-Nicolson scheme is used to model the propagation in a bulk media with equivalent effective parameters. An analytical procedure allowing to convert...
In this work we present a novel algorithm based on a subgridding boundary condition, for the subcell treatment of conductive thin-layer in FDTD (SGBC). We show that this technique provides a robust late-time stability behavior, compared to classical impedance boundary condition (IBC) methods, with affordable computer requirements. The method is validated by means of high-frequency scattering problems...
