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 general framework for determining fundamental bounds in nanophotonics is introduced in
this paper. The theory is based on convex optimization of dual problems constructed from …

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 …

Fundamental bounds on antenna gain are found via convex optimization of the current
density in a prescribed region. Various constraints are considered, including self-resonance …

The tradeoff between radiation efficiency and antenna bandwidth, expressed in terms of Q-
factor for small antennas, is formulated as a multiobjective optimization problem in current …

One challenge in designing RF wireless bioelectronic devices is the impact of the interaction
between electromagnetic waves and host body tissues on far-field wireless performance. In …

Hybrid computational schemes combining the advantages of a method of moments

The optimal spectral efficiency and the number of independent channels for multiple-input-
multiple-output (MIMO) antennas in isotropic multipath channels are investigated when …

Modern antenna design for communication systems revolves around two extremes: devices,
where only a small region is dedicated to antenna design, and base stations, where design …

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