Spooky wave interference

[Kedas]

if electromagnetic radiation started flowing in reverse, back toward its source, it could cause serious confusion. But this is just what Cesar Monzon, a Senior Scientist at Enig Associates, Inc., in Silver Spring, Maryland, has discovered. In a recent study, he theoretically demonstrates that, under special conditions of geometry, location, and frequency, power may flow backwards in the direction of its source. The study is published in a recent issue of Physical Review Letters.

I dont understand it, indeed spooky, but sounds reminicent of tesla.

I'll have to read the article; I wonder if the net flow of energy is still outward and this is a localized effect.

Standing waves were mentioned in the comments and it got me wondering what properties standing EM waves would have?

Not that different from moving ones; you get them all the time in resonant cavities, e.g. some types of lasers
