Abstract

The optical properties of surface plasmons at the resonant wavelength depend on the geometrical nanostructure of materials, refractive indices, thickness [materials and dielectrics], and shapes of the formation unit cell #nanoantennas. In this study, we take different shapes of plasmonic nanoantenna structures with a prototype of single and dual U- shapes as a common part to format a unit cell of nanoantenna by adding T and L-shapes based on a different dielectric such as, a silicon nitride, #magnesium fluoride, and aluminium oxide, with gold as a variation of refractive indices. A single U-shape provides a dual spectral resonance at a wavelength range of [500-950] nm. Thus, in these proposed structures, we try to achieve a triple band with the best #transmission and field enhancement distributions (electric field intensity and magnetic field intensity), and we design and simulate these fractals by using the 3D- finite difference time domain method Lumerical program with an incident source between a visible to infrared range. From the results, the triple bands have a wide range of applications in medicine as biosensors and in communication systems foptical modulators].Nanoantenna is a nanoparticle of #metallic structures designed to deal with light [1,2]. The principles of working such a device is to improve the energy conversion between the nanoantennas and free radiation field [3].
