One limitation is that the device can only perform one type of camouflage (thermal or visual) at a time, not both at once because the visual signature is dependent on the temperature of the pixels.
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 ...
A camouflaged soldier almost invisible to the naked eye may light up like a Christmas tree on a high-end thermal imaging device, which is why advanced thermal detection capabilities are among the ...
