plasma stealth

I’m sure everybody has heard about it, plasma stealth. Supposedly the Russians are working on this system. It could revolutionise air warfare if it ever worked. Nowadays stealth technology relies on making some sacrifices in other areas, like aerodynamics and weapons loads.
I’ve read a short article on it and I must admit that I think it should work in theory (although I’m not trained in theoretical physics).
But more importantly, will it work in practice, i.e. can it be made small enough to fit in an aircraft?
Any thoughts????
