□ 연구개요
최종 목표
· Phase change materials, quantum wells, electrochromic dyes, ferroelectric materials, photonic crystal or plasmonic resonators have all been investigated for active visible/IR camouflage. However, response speed, power consumption, low tunability, narrow spectral window, manufacturability, and cost are all significant concerns.
· The fabrication of assembled nanostructures with the desired configuration for metamaterials using magnetoplasmonic (MagPlas) nanomaterials, in which the instantaneous and anisotropic nature of magnetic interactions provides a unique approach for assembling MagPlas nanoparticles (NPs).
· Magnetic dipole-dipole interactions have been extensively studied as the driving force for NP and superparticle self-assembly, with the advantage that magnetic fields can be delivered remotely and instantaneously.
