Theory and Application of Analytical Models for Thin-Wire Nanoloop Antennas

Full-wave modeling of plasmonic structures is a computationally expensive process since the electric field penetrates into the material. This modeling often requires volumetric meshing to fully resolve the electromagnetic interactions. As a result, analytical models are highly desirable in lieu of full-wave simulations. Though analytical models cannot be derived for all complex structures, an exact analytical model for nanoloop antennas has been recently developed. In addition to providing insight into the governing physics, this model enables rapid parametric studies and optimization capabilities greatly improving the design-cycle process. This paper presents a demonstration of the theory in the design of directive and reconfigurable loaded nanoloop antennas.
