Abstract: In nano-scale, the conducting materials are found to behave the dielectric properties with negative real part of the relative permittivities (known as plasmonic materials with the eB.ective dimensions ranging from 20 nm to 200 nm) and the dielectric materials are found to have diB.erent optical properties compared to the bulk properties (such as Si and Ge). Due to their peculiar optical properties, nanoscaled materials can be applied in optical coating, optical communications (optical waveguides), surface cleaning, etching, scattering enhancement equipment, and data storage. In this thesis, I have studied the optical properties including the enhancement of the scattering, the transmission properties of silicon nanorods, the control of shifting the frequencies of the plasmon resonances by coated nanostructures, and the potential applications of plasmonic materials, from simple to complex structures (for both single and multiple scatterers). Further more, various numerical and theoretical investigation methods are used for analyzing the electromagnetic and light scattering problems.
