Function
Finite-element time-domain analysis: simulations of electromagnetic
interference and pulsed-power devices
|
Description
EMP simulates electromagnetic pulses in 2D planar geometries and 3D cylindrical systems. The program employs unique finite-element
methods on conformal triangular meshes for accurate representations of
curved and sloped material boundaries. Run times are short, typically
a few seconds on a high-performance computer. EMP supports
matched-termination absorbing boundaries to simulate open-space
conditions. Spatial data can be analyzed quickly with integrated
interactive post-processor. This program generates quantitative data
and a wide variety of plots. The package also includes the Probe utility to plot temporal signals. EMP application areas
include microwave devices, particle accelerators, pulsed-power
generators and electromagnetic interference.
