Thesis Abstract
In this research work, two types of metal-clad TM-pass polarizers, transmission mode polarizer and reflection mode polarizer, are studied. In the first type, the TM polarized waves are transmitted with low-loss, while TE polarized wave are transmitted with very high loss. The second type of polarizer has corrugations in its structure. It functions by reflecting TM waves with low-loss, while the reflected TE polarized waves are highly attenuated. The reflection and transmission spectra of the reflection mode polarizer are calculated for different high-index buffer layer thicknesses, different number of grating periods, different groove depths and different length of metal-clad section. The Method of Lines (MOL) with the Cascading and Doubling Algorithm is applied to model the multi-layer waveguide structure with periodic corrugations. Higher-order approximations of the second derivative operator with appropriate interface conditions are used. The Perfectly Matched Layer (PML) absorber is used to absorb the radiated fields due to the presence of longitudinal discontinuities. (Download Abstract)
