摘要：
Characteristic mode analysis (CMA) is an eigen-analysis technique that is particularly useful for gaining insight into the radiating properties of arbitrary electromagnetic structures. This work reviews a numerically efficient implementation for solving the generalised eigenproblem that results from separating the Method-of-Moments (MoM) impedance matrix in its real and imaginary components. Furthermore, the approach undertaken to deal with the tracking of eigenvalues as a function of frequency is also explained. Finally, the usefulness of the CMA implementation and mode tracking approach is illustrated at the hand of an example.
