Time-Varying Metamaterials: Dynamic Transformation Optics and Parametric Phenomena
Abstract
This research program explored the following aspects of the electromagnetic interaction with time-varying media: 1) The physical processes suitable to dynamically induce large permittivity changes in specifically selected regions of space. This research thrust led to the formulation of the theory of a new class of surface waves termed Accumulation-Layer Surface Plasmons (ASP). 2) The resonant eigenmodes of metallic nanostructures embedded in media with time-varying permittivity, and the conditions of parametric regeneration and parametric resonance. This research thrust led to the development of the theory of Plasmonic Parametric Resonance (PPR). 3) Optical limiting effects relying on plasmonic parametric resonance. In this research thrust a new class nonlinear saturable absorber termed Plasmonic Parametric Absorbers (PPA) was introduced and theoretically modeled.4) The study of tunable extreme anisotropy. In this context we proposed a variety of electromagnetic and optoelectronic devices relying on metamaterials with tunable hyperbolic dispersion.
