EM.Tempo is a powerful time-domain electromagnetic simulator for full-wave modeling of 3D radiation, scattering and propagation problems. It features a highly efficient Finite Difference Time Domain (FDTD) simulation engine that has been optimized for speed and memory usage. EM.Tempo brings to your desktop the ultimate in computational power. Its FDTD solver has been parallelized to take full advantage of multi-core processor architectures. With a large variety of geometrical, material and excitation features including open-boundary and periodic structures, you can use EM.Tempo as a general purpose 3D field simulator for most of your electromagnetic modeling needs. New in 2013 is a hardware-accelerated version of the FDTD simulation engine that runs 30x-50x faster on graphical processing unit (GPU) platforms.

EM.Tempo is the outcome of evolution of our first-generation FDTD tool, EM.Lounge, which was introduced in 2004. The original simulation code utilized an FDTD formulation based on uniaxial perfectly matched layer (UPML) boundary termination. Further expansion of that code culminated in a far superior boundary termination based on the convolutional perfectly matched layer (CPML), which performs equally well for all wave incidences at any arbitrary angle. Additionally, EM.Tempo now has the ability to model laterally infinite layered structures. It also provides a robust spectral domain formulation of periodic boundary conditions for modeling arbitrary periodic structures with oblique plane wave incidences.  EM.Tempo's new advanced simulation capabilities are your key to understanding of wave interaction in complex media such as anisotropic composites or metamaterials.
