If you have an infrared(only)viewing vampire, he could be tricked?
Boffins in the States say they have designed a "glass cloak" which renders objects within it invisible in the infrared spectrum. Prof Elena Semouchkina and her colleagues developed the "cloak", which reportedly bends micron wavelengths around its interior. Micron-length waves are in the near infrared, the part of the …

I have wondered about the possibility of snipers having their own "thermal invisibility shack" or outfit. Blocking the radiated heat seems straightforward-ish, the suit could be water cooled. BUT, where does the heat go? Clearly a hollow-tree exhaust is ineffective! In fact ANY kind of exhaust is a give-away, so a means of collecting heat for later release is needed. Is there any way to achieve this?
I've just noticed the prevalence of the word boffin in Lewis Page's generally entertaining articles. Why does he insist on using this word so frequently when referring to scientists? As far as I'm concerned it's akin to calling all IT professionals geeks or journalists journo's. It hardly portrays scientists in a positive light. Okay, sometimes it might be deserved but please give the poor people a break.
From the abstract it seems to have some grating patten cut into it. Presumably if it were just the material they could whip up a (small) batch of there own and. Gratings normally need to be *below* the wavelength of what they are trying to affect. So we are in wafer fab territory (not *deep* in, Mercury vapour lamp at c300nm should be up for the job) but glass etching is typically Hydrofloric Acid which is *very* nasty, unless you go with an electrochemical method (amazingly glass *can* be electrochemically machined and there are several papers on it from Korean and Japanese researchers).
So all I need is to take a thermally invisible greenhouse and put it *inside* a visibly invisible tin shed and I can sit inside the whole thing all invisible like.
Wait.....Ultraviolet you say?
Mine's the one that looks suspiciously like an enormous set of Matroska dolls coated in radar-reflective paint, or it would if you could see it.....
