Overview

OpenModes is a code aimed at solving the modes of open electromagnetic structures. Using these modes, broadband models of these elements can be created, enabling excitation, coupling between them and scattering to be solved easily.

Potential applications include metamaterials, (nano) antennas and other systems based on scattering from resonant elements. It is based on a fully numerical model of the system created using the method of moments (MOM).

The techniques used in this package, and the scientific results obtained, are described in the following publications and presentations:

• Interference between the modes of an all-dielectric meta-atom, 2017 paper or 2016 arXiv preprint
• Resonant dynamics of arbitrarily shaped meta-atoms, 2014 published paper or 2014 arXiv preprint
• Modes in open metamaterial and nanophotonic systems, web presentation.

This program was written by David Powell, a Senior Lecturer with the School of Engineering and Information Technology at the University of New South Wales, Canberra Campus.
