After that, maybe they could try writing a remotely accurate summary, too! The summary is borderline gibberish, as it is impossible (in linear materials) for EM fields to "deflect" each other.
This "cloak" is interference-based, using active dipoles to generate a field that cancels the scattered field in the forward (0 degree) and backward (180 degree) directions. It's a clever piece of work, but there are fairly hard limits to the how wide an angle such techniques can cover, and moving from an essentially 2D scenario to full 3D increases the complexity enormously, although I'd love to see them try it.
