  journal={arXiv: Applied Physics},
We present a simple and efficient Finite-Difference Time-Domain (FDFD) scheme for simulating dispersive (Lorentz-Debye) bianisotropic metasurfaces. This scheme replaces the conventional FDTD update equations by augmented update equations where the effect of the metasurface, positioned at a virtual node (or node plane) in the Yee grid, is accounted for by judiciously selected auxiliary polarization functions, based on the Generalized Sheet Transition Conditions (GSTCs). This scheme is…

We propose a simple and robust method for simulating bi-anisotropic metasurfaces as electromagnetic spatial discontinuity problems in the Finite Difference Frequency Domain (FDFD) scheme. The method
Efficient Analysis of Metasurfaces in Terms of Spectral-Domain GSTC Integral Equations
Compared with the finite-difference and finite-element techniques that require meshing the entire computational domain, the proposed technique reduces the problem to the surface of the metasurface, hence eliminating one dimension and providing substantial benefits in terms of memory and speed.

Computational Analysis of Metasurfaces
This paper presents the computational analysis of metasurfaces via the GSTC-susceptibility approach, and shows that this analysis plays a crucial role in the holistic design of metAsurfaces and overviews recently reported related frequency-domain (finite-difference frequency- domain, spectral-domain integral-equation, and finite-element method) and time- domain ( finite-Difference time-domain) computational techniques.
