Abstract

Plasmonics is a new and exciting field that has the potential to advance many different types of technology, from information processing and energy harvesting to sensing and imaging. The broad field of plasmonic materials and their potential to improve the functionality of cutting-edge technologies are examined in this thesis.

The thesis explores the synthesis, characterization, and manipulation of plasmonic materials after providing an overview of the basic ideas behind plasmonics. Their distinct plasmonic properties and possible uses are clarified by a thorough investigation of a variety of materials, including noble metals, two-dimensional materials, metal oxides and hybrid structures.

A thorough analysis of the Finite-Difference Time-Domain (FDTD) simulations used with different plasmonic materials is presented in this thesis. The theoretical foundation for FDTD simulations and their use in the investigation of plasmonic phenomena is established at the onset of the study. It then goes on to examine the properties of various plasmonic materials, such as noble metals, 2D materials and hybrid structures. The optical response, near-field enhancements, and dispersion properties of these materials are examined and contrasted using thorough simulations. This understanding of these plasmonic behaviors is utilized to control and manipulate a material’s performance and functionality in a particular technology. Using FDTD simulations, the thesis explores how material parameters, including size, shape, and dielectric constant, affect the plasmonic properties. Through the systematic variation of these parameters, valuable insights can be obtained regarding the optimization of plasmonic devices and systems' performance.

The thesis also discusses new developments and avenues for future research in plasmonics, including the creation of novel materials, the investigation of hybrid plasmonic systems. It also addresses the difficulties and restrictions associated with using FDTD simulations to model plasmonic materials, including issues with accuracy and computational complexity.

All things considered; this thesis offers an in-depth overview of how FDTD simulations are used to study different plasmonic materials. Through clarifying the optical characteristics, investigating dependence between parameters, and assessing new materials, it advances the field of plasmonics research and makes the creation of creative plasmonic systems and devices easier.
