FDTD.module

EM.CUBE's FDTD.module brings to your desktop the ultimate in computational power and modeling versatility. EMAGWARE has infused the functionality of its older EMLOUNGE product into EM.CUBE's new fdtd.module. Full-wave solutions of complex 3-D electromagnetic radiation, scattering and propagation problems are generated utilizing a highly efficient finite difference time domain (FDTD) simulation engine that is optimized for speed and memory usage.

You can define linear or nonlinear lumped circuits and connect them between any two adjacent nodes of the FDTD mesh. An integrated SPICE-type circuit simulator analyzes the circuit at every time step in synch with the FDTD kernel in a self-consistent manner. EM.CUBE's FDTD.module is your key to understanding of wave interaction in complex media such as ansiotropic materials or 3D periodic metamaterials.
