Non-radiative modes widely exist in the perfect electric conductor systems whose boundaries are closed surfaces, and have had many engineering applications. However, the non-radiative modes cannot be constructed by traditional electric field integral equation (EFIE)-based characteristic mode theory (CMT). The EFIE-based CMT is generalised, such that it can efficiently construct non-radiative characteristic modes (CMs), and it is found out that the non-radiative CMs and traditional internal resonant eigenmodes are one-to-one correspondence.
