Controlling and bending light around an object so it appears invisible to the naked eye

Basically, a two-phase operation is involved here. The device enables thermal cloaking in the 1st phase, followed by thermal camouflage in the 2nd phase. In diagram (a1) the inner layer of the cloak swings into action, eliminating the thermal signature generated by the “man” hence making the ”man” disappear. This inner layer provides complete insulation and thus ensures that no thermal signals can be detected, effectively making the target object disappear. In (c1), the 2nd (outer) layer goes into action, converting the thermal signature to that of two “women” (d1). It is able to do this by receiving and translating the thermal signature of the actual two “women” -- hence transforming the original shrouded ‘man’ into two “women”.
