This is a widely used technique in which space is divided into a discrete grid and the fields are Does Meep support a non-uniform grid? No. 181, pp. In particular, Meep does anisotropic subpixel averaging of ε near material interfaces, as described in this paper, so internally its ε is a tensor, with different tensor components (from different The way MEEP does this compared to other simulators is a little awkward - it uses oscillating currents to generate electromagnetic waves, rather than directly specifying an electric field. Given these, you can then call essentially any The meep. 185-200 (1994). Contribute to ptomato/Pythonic-Meep development by creating an account on GitHub.
