Characteristic Mode Decomposition Using the Scattering Dyadic in Arbitrary Full-Wave Solvers
(2023) In IEEE Transactions on Antennas and Propagation 71(1). p.830-839- Abstract
Characteristic modes are formulated using the scattering dyadic, which maps incident plane waves to scattered far fields generated by an object of arbitrary material composition. Numerical construction of the scattering dyadic using arbitrary full-wave electromagnetic solvers is demonstrated in examples involving a variety of dielectric and magnetic materials. Wrapper functions for computing characteristic modes in method-of-moments, finite-difference time domain, and finite element solvers are provided as supplementary material.
