Nearly all practical applications of the theory of characteristic modes (CMs) involve the use
of computational tools. This article is the second in a series of five on CM–. Here, we review …

A unification of characteristic mode decomposition for all method-of-moment (MoM)
formulations of the field integral equations describing free-space scattering is derived. The …

This article presents a novel approach for computing substructure characteristic modes. This
method leverages electromagnetic (EM) scattering matrices and spherical wave expansion …

The effect of mutual coupling between an antenna and an arbitrary scatterer on both the
reflection coefficient at the antenna input terminal and the total radiated field is investigated …

A hybrid approach for the computation of performance limitations for implanted antennas is
presented, taking radiation efficiency as the optimized metric. Ohmic loss in the antenna and …

Harmonic generation in the scattered fields produced by a dielectric sphere coated with a
time-varying conductive shell is studied using a Mie theory approach hybridized with …

A combination of two numerical techniques of computational electromagnetics, namely,
method of moments and vector spherical wave expansion, is used to show performance …

We investigated how to construct low-order subspace basis sets to accurately represent
electromagnetic (EM) fields generated within inhomogeneous arbitrary objects by radio …

The problem of substructure characteristic modes is developed using a scattering matrix-
based formulation, generalizing subregion characteristic mode decomposition to arbitrary …

Performance limitations for implanted antennas, taking radiation efficiency as the metric, are
presented. The performance limitations use a convex optimization procedure with the …
