Abstract
AbstractIn this article, Terahertz spherical dielectric resonator antenna (DRA) is mathematically formulated and simulated at 511 THz for LiDAR and retinal photoreceptor applications. Titanate DR element is used at optical design frequency. It is validated with good S11, radiation pattern and 5.6 dBi gain plots using HFSS simulator. Unique mathematical formulation on super directivity and radiated states is formulated for the first time. The proximity coupled feed is used with laser Gaussian beam excitation. The silver nano waveguides is used to provide feed mechanism to terahertz DRA. This DR design at optical frequency can be used for wireless sensing and communication applications. It has novel geometry.
