This paper introduces an efficient method of characteristic mode decomposition for multi-structure systems. Our approach leverages the translation and rotation matrices associated with vector spherical wavefunctions, enabling the synthesis of a total system's characteristic modes through independent simulation of each constituent structure. We simplify the computationally demanding translation problem by dividing it into three manageable sub-tasks: rotation, z-axis translation, and inverse rotation, which collectively enhance computational efficiency. Furthermore, this method facilitates the exploration of structural orientation effects without incurring additional computational overhead. To demonstrate the effectiveness of our approach, we present a series of compelling numerical examples that not only validate the accuracy of the method but also highlight its significant advantages. |
