The emphasis of this report is on the project undertaken and knowledge gained from working on final year project. In this project, the properties of plasmonic waveguide is studied and applied. By implementing using various materials available, wave guiding capability is enhanced. The report comprises an overview of the description and analysis of the project and subsequent assignments undertaken. The main projects and tasks included in this report are: 1) Investigation on extended plasmonic wave guiding structure (dielectric – metal – dielectric) constructed with high dielectric constant intermediate layer using reflection pole method (RPM) for gold, silver and copper. 2) High and low dielectric constant silicon compositions are used as intermediate layer to test wave guiding capabilities. 3) Several silicon dioxides are used as intermediate layer and semi-infinite layer to get critical intermediate layer thickness for longest range wave traveling. 4) Metal – dielectric – metal and asymmetric structures are investigated and documented in this report. In this project I have learnt detailed process flow of research project as well as some points of view about the applications of plasmonic waveguide. My problem solving skills and self independent attitude are enhanced. This will be beneficial to my future study.
