Abstract: The interface between a metal and a dielectric at optical frequencies supports longitudinal surface charge density oscillations, known as Surface Plasmons (SP). The existence of SPs is possible only if the metal have a negative dielectric constant at the corresponding optical frequency. In this paper the propagation characteristics of Surface Plasmon Waves (SPWs) which exists on noble metals like gold (Au), silver (Ag) and aluminium (Al) due to the formation of Surface Plasmon Polaritons (SPPs), have been evaluated theoretically and simulated with the help of MATLAB programming language. The variation of the propagation constant, the attenuation coefficient, penetration depth inside the metal and the dielectric and the variation of the spot size width with the propagating wavelength have been determined. It has been found that highly conducting metals Au and Ag provide a strong confinement to the SPWs than Al at optical frequencies as the spot size width of the for!
mer is found to be nearly 10 µm less than that of the later.
