The Green's function is an auxiliary function that needs to satisfy different conditions according to the practical mathematical models applied to the problems. The required conditions do not have to be Helmholtz equation. Two possible common conditions are summarized in this reply, i.e., the Maxwell reciprocity and the corresponding homogeneous boundary conditions.
