dc.description.abstract Tailoring the radiative properties of periodic micro/nanostructures can be used as an efficient way to create devices which have applications in energy harvesting, bioengineering and optical sensing. These structures are analyzed by a rigorous solution of the electromagnetic wave phenomena at the interfaces. The thesis explores the application of rigorous coupled-wave analysis (RCWA) method to study the optical responses of microstructure arrays. First section of the thesis elucidates the various mechanisms which are responsible for causing enhanced light absorption in inclined parallel plate grating arrays. Illustrative evidences of surface plasmon and magnetic resonances are provided by one and two-dimensional plots prepared by RCWA. Analytical agreement with visual data is obtained through use of LC circuit models. Finally, the effects of different geometric parameters on the resonance conditions are investigated. The second part of the thesis deals with application of RCWA to study the effect of light scattering on inclined silver nanorod (AgNR) arrays grown on compact disc (CD) gratings. Depending on the manner in which AgNRs are oriented with respect to CD gratings, they exhibit different optical behavior to incoming light. Effects of both incident light polarization and AgNR orientation with respect to the grating have been studied through the use of RCWA and effective medium theory. Calculated results are compared with experimental values and good agreements are observed for total reflection as well as trends of individual diffraction orders. en_US
