FDTD Solvers

Finite-difference time-domain (FDTD) is a widely used computation modeling technique that is one of the means to computationally model many scientific and engineering problems dealing with electromagnetic wave interactions with material structures.

FDTD modeling applications range from the analysis and optimization of antennae (for radio, television and radar), to the design of microwave circuits and the influence of electromagnetic fields on the human body (wireless communications devices, digital interconnects, and biomedical imaging/treatment) to visible light (photonic crystals, nanoplasmonics, and biophotonics).
