Since XFdtd^® includes frequency-dependent dielectric and magnetic materials, it is capable of making three-dimensional calculations for double negative materials, also called negative index materials and meta-materials. Learn how XFdtd can be applied to these new materials.

A special feature of XFdtd^® is its ability to include Timed Switches in calculations. This allows the user to change the configuration of the calculation geometry during a calculation.

This example demonstrates the ability of XFdtd^® 6 to include anisotropic dielectric materials with off-diagonal terms in the permittivity tensor.

XFdtd^® provides a wide variety of excitations, including both voltage and current sources and series/parallel RLC circuits. In this example a parallel plate capacitor is charged, first by a current source, then by a LaPlace static potential solver.
