Transformation optics: from macroscopic to subwavelength scale (Conference Presentation)
Author(s): Yu Luo

Paper Abstract

Transformation optics is a general design tool that is as intuitive as the ray optics, but exact at the level of Maxwell’s equations. It provides a direct link between a desired electromagnetic phenomenon and the material response required for its occurrence. In this talk, I will give an overview of some recent progress of transformation optics, with a special focus on its applications at the subwavelength. 1. I will show how to use this strategy to design a finite subwavelength particle that can harvest light over a broadband spectrum like an infinite plasmonic system; 2. I will discuss how the conformal transformation approach can help us understand some complex plasmonic phenomena, such as fast electron interaction with singular plasmonic particles, van der Waals interaction at extreme scales, compact dimensions in 2D singular plasmonic surfaces, etc.
