Paper Abstract

The thermal analysis (TA) of the wave propagation in the mid-wave (MWIR) and long-wave (LWIR) infrared bands performed by the direct solutions of the Maxwell electromagnetic (EM) problem with numerical methods is used to propose the design of metamaterials suitable for a new type of thermal vision camouflage, that can be prepared using a nano particle lattice in the IR bands. This lattice, called photonics band gap devices (PBG) or more in general photonic crystal (PhC) works on IR photons providing absorbing, transmission and reflecting bands. All the optical properties are function of the specific nano design tuned in the IR wavelength.
