Abstract: This paper presents an analysis of the far-zone electromagnetic scattering ofrectangular waveguides terminated by a perfect electric conductor and by a medium material by means of the generalized scattering matrix technique. The optical methods used in analysing the scattering matrixes of a rectangular waveguide involve use of the method of equivalent currents for analysing the [S11],the edge back-scattering matrix of the apture, of the physical optics and the physical theory of diffraction for analysing the scattering matrix [S12] of waveguuide modes, of the reciprocity theorem for determing the exciting matrix [S21] of waveguide modes from [S12],and of the transmission line theory for analysing the [Sb],the reflection matrix of the termination. Finally, the numerical calculation is mode on the basis of theory analysis, the results are proved, to be superior to that of Witt's.
