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 that has been optimized for speed and memory usage. Accommodating a large variety of geomtrical, material and computational features inlcuding open-boundary and periodic structures, EM.CUBE now provides a general purpose 3-D field simulator to meet all your electromagnetic modeling needs. The module's new advanced simulation capabilities are your key to understanding of wave interaction in complex media such as ansiotropic composites or metamaterials.

EMAGWARE has fully transitioned the functionality of its older EMLOUNGE product into EM.CUBE's FDTD Module. The integration of EMLOUNGE into EM.CUBE signals EMAGWARE's continued commitment to development and deployment of powerful, affordable modeling software.
