When solving electromagnetic scattering problem with T-matrix method, if the scattering obstacles have point-group symmetry, i.e. remaining unchanged under the group transformation, we can obtain the relationship between geometric symmetry and symmetry of elements in T matrix by the usage of group theory. In this way we can foresee the exact values of some matrix elements, as well as relations between elements, which would save numerous running time in numerical calculation.
