Abstract

The efficient harvesting of electromagnetic waves by subwavelength nanostructures can result in perfect light absorption in the narrow or broad frequency range. By the use of proper material and design configuration, it is possible to realize these lithography-free light perfect absorbers in every portion of the EM spectrum. This, in turn, opens up the opportunity of the practical application of these perfect absorbers in large scale dimensions. In last couple of years, we adopted these lithography-free techniques in many applications including photoconversion, photodetection, light emission, sensing, filtering and thermal camouflage. This presentation will summarize our recent accomplishments in this field.
