| It's not a matter of light amplification, but of harmonic distortion. Again, I'm assuming quite a lot, here, because the article leaves much to be desired as far as elucidating theory goes. But, I think the idea is to build standing waves of electrons to interact with incoming photons of specific frequencies. The result isn't boosted light, but a semi-coherent reflection, instead. Our perception systems are geared to respond to non-coherent reflections. A semi-coherent one, therefore, would seem very difficult to focus on -- much like a mirage. (A fully coherent reflection would be like staring into a laser -- not recommended.) So, in effect, what this "invisibility shield" does is hide a real, solid object behind a shimmering mirage. Anyone who lives in an area with hot-enough summers knows this can happen even naturally. The big difference is that a natural mirage refracts light, whereas this shield is itself a solid object and reflects light. |
