EM.CUBE's FDTD.module brings to your desktop the ultimate in computational power and versatility. 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 optimized for speed and memory usage. You can define linear or nonlinear lumped circuits and connect them between any two consecutive nodes of the FDTD mesh. An integrated SPICE-type circuit simulator will analyze the circuit in synch with the FDTD kernel in a self-consistent manner.

EMAGWARE has fused the functionality of its EMLOUNGE product into EM.CUBE's new fdtd.module. The integration of EMLOUNGE into EM.CUBE signals EMAGWARE's continued commitment to development and deployment of powerful, affordable 3-D EM simulation software.
