Abstract

In this thesis, a plasmonic nano-slit lensing was investigated theoretically by demonstrating planar lenses based on nano-scale slit arrays in a metallic film. The lens structures consist of optically thick gold films with micron-size arrays of closely spaced and nano-scale slits of varying widths. COMSOL Multiphysics Time-Harmonic Finite-Element (THFE) simulation software was used to design and simulate the research. It was apparent that there was a slight increase of the maximum power as the air slits' widths increase. Whereas, it was also apparent that there was a slight decrease of the maximum power as the gold film's thicknesses increase. Wavelength-scanned was done at various wavelengths (0.8 μrn < λ < 2 μrn) to see the changes of focusing pattern (to show different maximum power).
