Research studies project report ; no. ISE-21-01 A research study submitted in partial fulfillment of the requirements for the degree of Master of Engineering in Nanotechnology, School of Engineering and Technology Research report (M. Eng.) - Asian Institute of Technology, 2021 Optical antennas are one of the emerging concepts in the field of optical physics. The purpose of an antenna is to convert energy of free propagating radiation to localized energy and vice versa. Such antennas are most promising at nanoscale, operating at optical frequencies, called as Optical Nano-Antennas. Optical nano-antennas typically utilize the unique morphological and optical properties of nanostructured materials, which behave as strongly coupled plasmas at optical frequencies. In this research, we conducted a theoretical study on optical nanoantenna and investigation of radiation patterns using FDTD analysis. This work involves the optical nanoantenna which exhibit high scattering which can be used to control the light propagation across the surface. an organised analysis of single and periodic array of optical nanoantenna through air dielectric is done. The scattering calculations shows high forward directivity of different nanoantenna elements.
