Abstract
In this letter, a new algorithm for surface boundary condition of thin layer is proposed to incorporate the effect of lossy and dispersive media. The 1-D wave equation inside the layer is recast as a Sturm-Lioville problem; the Green's function is analytically computed and used to relate tangential electric and magnetic fields. The knowledge of poles and residues allows one to obtain a state space realization, suitable for time domain implementation in finite-difference time-domain methods..File in questo prodotto:
