Abstract
In this study, we have investigated the optical property of single and coupled gold nanoparticle (AuNP) using the finite-difference time-domain (FDTD) method. The initial study facilitated us to simulate the bowtie antenna where we investigated the key performance parameters of optical nano antennas such as extinction efficiency, plasmon coupling, near -and far-field enhancement, transmission and reflection as a function of size, and separation. The findings of this study will be beneficial to design a more complicated optical nano antenna, tuning the frequency in THz range varying the size, shape and geometry and also to meet the future need of 6G communication and beyond.
