The simulation of electromagnetic scattering in piecewise homogeneous media using unstructured grids
This paper presents a method for simulating, in the time domain, the scattering of electromagnetic waves in piecewise homogeneous media. The method employs an explicit Taylor–Galerkin approach, implemented on a general unstructured triangular grid, with the electric and magnetic fields approximated...

| description | This paper presents a method for simulating, in the time domain, the scattering of electromagnetic waves in piecewise homogeneous media. The method employs an explicit Taylor–Galerkin approach, implemented on a general unstructured triangular grid, with the electric and magnetic fields approximated in a continuous piecewise linear fashion. All boundary and material interface conditions are weakly applied in an integral form, following a characteristic decomposition of the solution. A number of simple examples, for which exact scattering width distributions are available, are included to demonstrate the numerical performance of the proposed procedure. |
