2.5 Remcom

Remcom provides a large number of simulation software packages for electromagnetic analysis [5]. One of these products provided by Remcom is XFdtd. XFdtd is a full wave three-dimensional finite difference time domain electromagnetic solver. Models described by different CAD file formats can be easily imported, edited, and then exported to CAD format again. XFdtd offers a fast meshing algorithm and mesh preview before calculation. It can model complex nonlinear and frequency-dependent electric and magnetic materials, nonlinear devices, and anisotropic materials. Due to its parallelization capability huge applications can use computer clusters. XFdtd supports XStream hardware FDTD (another product of Remcom), which utilizes high speed graphics processors for increased calculation speed.
