【英文介绍】

The Electromagnetics Toolkit includes two solution programs. 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. WaveSim models electromagnetic waves in 2D structures. The program finds resonant modes of cavities and waveguides and also handles scattering solutions. High-performance matched termination layers represent open-space conditions. WaveSim determines both near- and far-field solutions and handles absorption resulting from resistivity or imperfect material response. Both programs feature integrated graphical post-processors for plots and solution analysis. The package includes the Probe utility for temporal signals generated by EMP.
