OpenModes 1.2.0

An eigenmode solver for open electromagnetic resonantors

A Method of Moments (Boundary Element Method) code designed to find the modes of open resonators such as meta-atoms (the building blocks of metamaterials), (nano) antennas, scattering particles etc. Using these modes, broadband models of these elements can be created, enabling excitation, coupling between them and scattering to be solved easily.
