A subcell FDTD Scheme implementation for thin slot modeling

Autor: Cabello N. Miguel Ruiz, Antonio J. Martin Valverde, Borja Plaza Gallardo, Malte Frovel, David Poyatos Martinez, Amelia Rubio Bretones, Salvador Gonzalez Garcia

The finite-difference time-domain (FDTD) method is not able to efficiently model thin features without a drastic reductions of the spatial mesh size, potentially yielding an unfeasible use of memory and CPU requirements. In this work we propose two s

A novel conformal technique for the finite-difference time-domain (FDTD) method is proposed to deal with curved and arbitrarily oriented lossy thin panels. This is formulated as an extension of the existing conformal relaxed Dey–Mittra (CRDM) metho

This contribution presents a comparison of the stochastic FDTD [1] (S-FDTD) and Monte Carlo methods, for the analysis of thin-wire antennas with the Holland formulation [2]. An analysis is made on the effect of crosscorrelation between the variables

In this paper, we show a simulation strategy for composite dispersive thin-panels, starting from their microscopic characteristics and ending into a time-domain macroscopic model. In a first part, we revisit different semianalytic methods that may be

In a previous work, we presented a hybrid implicit–explicit Crank–Nicolson finite-difference time-domain method for treatingmultilayered lossy thin slabs. The main advantage of this methodwas its capability to overcome certain late-time stability
