Abstract
Noble metal nanoparticles are capable of confining resonant photons in such a manner as to induce coherent surface plasmon oscillation of their conduction band electrons, a phenomenon leading to two important properties. Firstly, the confinement of the photon to the nanoparticles dimensions leads to a large increase in its electromagnetic field intensity and consequently great enhancement of all the nanoparticle’s radiative properties, such as absorption and scattering. Secondly, the strongly absorbed light by the nanoparticles is followed by converted efficiently into thermal to kill harmed cells without harming the surrounding healthy cells. In this thesis, the High Frequency Structure Simulator (HFSS) software is used to compare the performance of different proposed shapes of nano-particles: nano-sphere, nano-rod, nano-sandwich, nano-circle, nano-ring, nano desk and nano-rectangular shape. Each of the proposed shapes has been put in two different forms: Single element and array. The reflection coefficient 𝑆11 is taken as a measure for the back scattering of the different structures. Also, an experimental work is achieved to check the simulation results at the Advanced Technology & New Materials Research Institute at City of Scientific Research & Technological Applications in Borg Elarab city lab.
