"absorption/ shielding <0.5mm thick, <1% reflectance... flexible, durable maintaining shape even after being folded/ unfolded thousands of times, making suitable for use in rollable phones/ wearables... synthesized magnetic material altering ferrite crystal structure... incorporated conductive patterns on film’s back side... adjusting conductive pattern's shape reduces electromagnetic wave reflection at specific frequencies... carbon nanotube thin film applied to the back... smartphones, autonomous vehicle radar”
