scuff-em is a free, open-source software
package for analysis of electromagnetic scattering problems using
the boundary-element method (BEM). (The BEM is also known as the
"method of moments.")
The scuff-em suite consists of two
components: a core library that implements the essential
algorithms of the boundary-element method, and a set of
application programs built atop the core library for
solving specific problems in various fields of physics and engineering.
The core library, libscuff, is written in
C++ but may also be accessed from
python. Extensive documentation of
the programming interfaces is available from the links below.
The application programs, implemented as console-based command-line
utilities, include tools for (1) general electromagnetic
scattering of arbitrary incident fields from compact or
periodically extended scatterers; (2) computation of
Casimir forces and Casimir-Polder potentials
in complex geometric and material configurations; and
(3) modeling of RF and microwave devices,
including computation of multiport network parameters and
radiated fields for antennas, lumped elements, and other
RF devices.
The entire scuff-em suite is free software
distributed under the
GNU GPL.
scuff-em stands for
Surface CUrrent/Field Formulation of
ElectroMagnetism.
This is a reference to the underlying solution methodology used by
scuff-em and other BEM solvers, in which
we solve first for surface currents
(including both electric (K) and magnetic (N)
currents, as cartooned in the scuff-em
logo), then use these currents to compute the scattered fields.
