OPTICS SOLUTION
SEMCAD X Matterhorn Optics Solution incorporates a comprehensive material database, including Debye, Lorentz, Drude, Drude-Lorentz, Kerr-effect, and Raman-scattering materials, for modeling passive optical devices based on FDTD methods.
Optimal simulation speed is achieved with native GPU and message-passing interface (MPI) accelerations, which were developed by our team, who first introduced EM-accelerated solvers together with Acceleware in 2006.
The optimization tool allows parameters of different dispersive models (Debye, Lorentz, Drude, and Drude-Lorentz combination) to be obtained for a given material (user-defined or imported from a text file).
Various easy-to-use Python routines for performing frequent tasks and an extensive application programming interfaces (API) for deep access to the SEMCAD X Matterhorn framework are provided.
