This paper proposes a general characteristic mode-based design procedure of simple three
steps for wideband circularly polarized (CP) antenna design. First of all, the characteristic …

Entire-structure-oriented work-energy theorem (WET) framework is used to establish the
characteristic mode theory (CMT) for material scatterers. Diagonalizing driving power …

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 …

Characteristic mode analysis (CMA) is becoming a popular tool to analyze radiation and
scattering problems. However, some preliminary studies revealed that the conventional full …

The theory of characteristic modes (TCM) is presented for arbitrarily shaped 3-D structures
including perfect electric conductors (PECs) and homogeneous penetrable objects. It is …

In this communication, we develop a surface integral equation-based sub-structure
characteristic mode (CM) formulation to accurately analyze the resonant modes of dielectric …

By studying solutions of various forms of the Poggio-Miller-Chang-Harrington-Wu-Tsai
(PMCHWT)-based characteristic mode (CM) formulations, we have found that the proper …

This is the second component of a two-part article dealing with a unification of characteristic
mode decomposition. This second part addresses modal tracking, interpolation, and the role …

A novel surface integral equation (SIE)-based theory of characteristic modes (TCM)
formulation is proposed for homogeneous penetrable bodies. Analytical expressions for the …

In this paper, the physical meanings and various computing methods of characteristic modes
(CMs) of dielectric and magnetic bodies are investigated. Two types of surface integral …
