【Abstract】 The Dirac-Symbol Method is reviewed briefly. In this paper, we define the dyadic Green’s functions as the generalized vector operators, the dyadic S function being the unit operator. Their Dirac-Symbol representations are then given. With the rectangular waveguide as a specific example, we may see that it is simpler to derive dyadic Green’s functions of electromagnetic field by Dirac-Symbol Method.更多还原
