Did he publish it anywhere??

No. Sadly, it got scrapped, thanks to those project rules. Half implementation meant half grades.
A professor over at IIT recommended that it was a waste because, so far, no one had been able to transfer beyond a few centimetres. That was the end of story. He modified it to suit the dissertation requirements, as it was necessary to get it approved by the committee. (I guess something to do with dipole design)
Still, that didn't stop him and as a side project he built a prototype after researching a bit, so nothing new, just implementation off some Hackaday forum posts and such but then again, time was limited during final year. Exams, placements, project.

what course r u in ? wireless charging seriously has its limitations.
imagine this, a cellphone charger requires power in the range of watts, but a cellphone transmitter normally works at below watt level, at 800MHz to couple GHz band, to communicate with distant towers, that too sometimes considered harmful.
on the other hand, induction cookers work at 50KHz to may be < 1 MHz bnad, delivering lotta EM power at a very short distance, without being any noticeably harmful.
collaborating those u may write out ur own antenna & propagation theory (may be with reflectors too) to find out a sweet point for wireless charging with a practical demonstration of all those theoretical calculations. many people have already worked on this, so it may perhaps be an interesting project at b.tech level, but thats all.
if u have queries, u may ask the guys at allaboutcircuits forum, some of them know the theories there.

Oh no, I'm not into those subjects and I've been out of college for quite a while, so, I don't remember much of 'Communication Theory' and 'Antennae and Wave Propagation'
The project was about 'Power Transfer'. Now, that is a broad term. Can be anything related to power. So no, charging the device was not the objective. But now that somebody actually has implemented it, I expect to see a working product in the near future. That Nokia charger never seemed like a 'True' wireless charger to me. This comes close, at least.
