“…More involved approaches have been developed for similar analysis of finite arrays through the use of modal properties of single array elements [73]. Numerical analysis of infinite uniform arrays has also been carried out through the use of problem-specific Green's functions, closely resembling the approaches taken in the analysis of objects above infinite ground planes [65], [74], [75].…”

Nearly all practical applications of the theory of characteristic modes (CMs) involve the use of computational tools. Here in Paper 2 of this Series on CMs, we review the general transformations that move CMs from a continuous theoretical framework to a discrete representation compatible with numerical methods. We also review several key topics related to computational CMs, including modal tracking, dynamic range, code validation, electrically large problems, and non-PEC techniques.

“…In recent years, a reduced matrix solution based on modal basis functions is proposed for fast solution of the reflectarray antennas [10]. More recently, a microstip reflectarray unit cell has been analyzed using the characteristic modes and the modal reflection phases are discussed for the first time [11].…”

Characteristic mode analysis of metal only unit cells of periodic structures is performed using Method of Moments based formulation. Ewald’s transformation is incorporated for a fast and cost efficient solution and the advantages over spatial Green’s function are discussed. The influence of the unit cell size on the characteristic modes is demonstrated. Various metal-only reflectarray elements are compared and their radiation characteristics are interpreted using the theory of characteristic modes. It is shown that characteristic modes of the unit cell can help us to understand the radiation and scattering behavior of the unit cell and this physical insight can be used in periodic array unit cell design.
