For one of my courses this year we have to design a demo/educational kit demonstrating an electromagnetic phenomenon, our group has chosen Wireless Power transfer.
Our current idea is to design a kit with two WPT antennas on a slider to demonstrate the effect of distance on the efficiency of the coils, and to have the coils interchangeable. The biggest problem we are currently facing is finding examples online of simple WPT systems proving numerical theory, we either find basic wound coil systems on the likes of instructables, or full thesis on designing an complex WPT system. I would like to ask if anyone knows of a relatively simple WPT paper (or website) which we could use as a starting point?
Here is a quick screenshot from Fusion 360 on Android of the initial design for the kit.
