In this paper, application of generalized network studied the theory of electromagnetic waves through the hole coupling . First introduced the principle of the method of moments , followed by solving the the aperture coupled problem , and the relationship of the two methods for solving generalized network method and eigenmode . Followed by the the singular integral problems encountered in the generalized network aperture coupling analysis , singular integral using the Green's function of the eight firstorder approximation formulas and other product transformation method for processing . The Green's function of the derivative of the singular integral with a singular point of the theory of generalized functions to eliminate processed . And calculate the the infinite conductor surface porous coupling aperture surface equivalent magnetic current distribution . Finally, a hole cavity coupling structure . First dipole characteristics of the holes , the nearfield approximation quasi  static distribution of farfield scattering field approximation for the dipole radiation field . According to this feature of the holes , and generalized network method to analyze the nature of the generalized admittance matrix , the equivalent magnetic current waves radiated from the commencement of the model used to ignore the highorder mode mutual coupling between the two holes , according to the network theory, generalized admittance matrix is equivalent to a two port network . Then analyzes the nature of the transfer admittance and transmission scattering cross section , we can see that the cavity resonance transmission independent of the size of the scattering cross  sectional face seam and cavity . The transmission scattering section of the media and the aperture size changes .
