A simple scheme for T-matrix retrieval with higher efficiency and accuracy by taking particle symmetries into account is presented. T-matrix is calculated using matrix inversion, where the matrix elements are numerically calculated. This proposed scheme additionally generate extra matrix elements using the particle symmetries and reciprocity. This process consumes little effort in terms of computations, while the retrieved T-matrix shows improved accuracy for geometric symmetries and reciprocity. We also study required symmetry operations depending on the symmetries of meta-atoms (point group), and the shapes of their T-matrices. This scheme allows efficient and accurate calculation of T-matrix of meta-atoms for further calculations and group-theoretical analysis. |
