Characteristic modes (CM) can be used to solve many radiation and scattering problems involving fully conducting structures. The basic concept is to use eigenvalues and eigenvectors of the characteristic mode equations of a certain topology, and to use these eigenmode currents to control the radiating structure's behavior. This is accomplished by understanding the overall reflection and radiation characteristics across the operating frequency band. More specifically, characteristic modes are effective for example in determining the best location for the excitation of a radiating structure. In this paper, a comprehensive overview is given of the different studies and their results obtained for different antennas that are based on the CM analysis method. A future perspective is given regarding the potential of this method in antenna analysis and design.INDEX TERMS Antenna analysis, characteristic modes, antenna optimization.

“…The modal stored energy approach for metamaterial inclusion is useful for selecting an inclusion to associate with an electromagnetic system like antenna. Already, many electromagnetic designs make use of modal approach such as evaluation of antenna Q-factor [20][21][22], selection of antenna excitation source [23], design of metamaterial inclusion for antenna application [24][25][26][27] and the study of electromagnetic structures [28][29][30]. This is due to the numerous advantages which include its independence of excitation source, applicability to arbitrary-shaped structures and the physical insight it brings into the behaviour of radiating structures [14,15].…”

Electromagnetic metamaterials are generally defined and classified in terms of their effective parameters. They are evaluated in the far-field which limits the evaluation of its near field interaction in some applications such as metamaterial inspired design. An alternative approach proposed in this paper is based on the modal stored energy of metamaterial inclusion. This approach is based on the surface current distribution which would address the challenge of metamaterial near-field application. This paper describes a method for quantifying the modal stored energy of arbitrary-shaped metamaterial inclusions based on the theory of characteristic modes. The theory of characteristic modes is independent of excitation, gives good physical insight into the behaviour of an inclusion and would be helpful for near-field application of metamaterials. The modal stored energy approach is also compared with the common effective parameter approach. It shows similarity in terms of the physical and qualitative analysis when far-field assumptions are accounted for. The broadside-coupled split-ring resonator and the S-shaped inclusion are considered. The physical and qualitative analysis based on the modal stored energy approach shows a good agreement with the effective parameter approach.
