Isn't total power/bit transmitted the most interesting point? Magnetic path loss in biological tissue is very well understood, see MRI. I don't understand how this is Ph.D. level work.

It is a relatively novel method for transmitting signals through the body with applications to body sensors, medical devices and ubiquitous computing. People have gotten PHD's on a lot less. Who are you to say it isn't worthy?
