This reference from 2007 wherr a lab at MIT demonstrated wireless power transfer, may be relevant for explaining inductive coupling and the idea that this is not radiative (far field) power transfer - correct me if this technology is fundamentally different:
Coupling has nothing to do with Emrod tech. Its intrinsically limited to low power and small range. It is also has a much more significant impact on health and safty.
Ok understood. The "near field" comment made me think it was the same thing... I don't understand how this works then (not a criticism, just a walking back from thinking I got it)
