Abstract:
This thesis formulates Green's function of periodic arrays of two-dimensional rectangular holes Perforated on a PEC film. Green's function of two-dimensional periodic free space in the spectrum domain is computed. Using Floquet theory and considering the holes as rectangular waveguides, Green's function of the structure is presented.For sub-wavelength holes in cut-off and propagating cases, numerical results are presented. The effects of changing the aperture's thickness and the number of required modes have been reported. The structure under a normal and oblique incident wave is investigated, and the high conformity of the presented model results and full-wave simulations is observed.In addition to the plane wave results, the results of periodic sources have also been investigated, and Green's function has very high accuracy. Due to the accuracy of the results in different cases, the Green's function is trusted, and the field profile is presented near the extraordinary transmission
