A new structure design enables a dual-function system for infrared camouflage and thermal management

Combining metallic glass with the Berreman mode of epsilon-near-zero (ENZ) thin films achieves a dual-function system for infrared camouflage and thermal management within an identical wavelength region of the atmospheric window. In recent research, metallic glasses were selected for their tunable optical properties, providing adjustable emissivity for versatile thermal camouflage while maintaining effective thermal management.
