Beamforming would be cool and might actually allow this to work, although I don't know with what efficiency.
That said, the tech just to locate the phones in space to allow the beamforming would be a significant accomplishment itself. But forming the beam or multiple beams to charge multiple devices is probably quite feasible.

That should be easier than trying to accurately locate the phone first so that you can aim a beam at it. If you can also make a reasonable initial guess of it's location (to within a few degrees) you could narrow down the guess and check search area considerably.
