MAXWELL3: A 3D finite element electromagnetic modeling code
Abstract
The simulation of electromagnetic coupling and scattering has grown in importance in recent years due to the vulnerability of integrated circuits to EMI. More specifically, there is a need for simulating electromagnetic scattering from, and coupling to, three dimensional objects. To satisfy the need for accurate, time domain modeling of 3D electromagnetic coupling and scattering MAXWELL3 was developed. The numerical method chosen requires the discretization of the model with a mesh generator. MAXWELL3 then uses the mesh and computes the time domain electric and magnetic fields by integrating Maxwell's curl equations. The output from MAXWELL3 can then be used with a post processor to get the desired information in a graphical form. MAXWELL3 is a linear, time domain, finite element code designed for simulation of electromagnetic fields interacting with three dimensional objects. The discretized model is defined by a collection of homogeneous, isotropic hexahedral elements (six faced, eight noded bricks) which need not correspond to a logically regular grid. Because the elements are not restricted to rectangular boxes, the problem space boundaries and interior surfaces can be of arbitrary shape.
