Abstract

Phase transition materials offer exciting opportunities to dynamically control the optical properties of photonic devices. As a special phase change material (PCM), vanadium dioxide (VO2) is an excellent alternative for thermal camouflage technology research. Due to the unique property of VO2, coupled with the metallic structure can enable the design of thermally reconfigurable absorbers that allow resonance tuning. We propose a very simple, multi-layered with metamaterial excellent thermal emitter nanoantenna. The size of our design is only 1365 nm for the infrared wavelength range from 0.8 to 12 µm. Concept silver (Ag), VO2, dielectric separator and silver (Ag) configuration are used for finite difference time domain (FDTD) analysis. The absorption band can be further expanded with more deposition layers with various metals. In this paper, a thermal camouflage mid-infrared adaptive metamaterial antenna based on a PCM metamaterial is designed to fit perfectly into atmospheric windows. The spectral properties of the structure were calculated using FDTD method. The distinctive feature of the proposed structure is that adaptations can be made by placing an ultra-thin VO2 interlayer between the metallic structures. We believe that the proposed design is very promising in terms of simple fabrication and modifiable aspects for wide-area broadband unity absorption.
