Did they have an amplifier connected to their transmitting coil? How did they send 60W over with a signal generator? Its impossible, they must've used an amplifier...anyone know of their setup?
Why did they choose 10 MHz? What is the purpose or design criteria for choosing the frequency of operation? They mentioned near field region and whatnot, but if you choose 100 KHz you're very much in the near field (0 to lambda/4) as well, so why 10 MHz? Also, they used distributed capacitance and inductance....why? Why can't you use regular coils and capacitors to achieve the same?
Why did they couple their source to their transmitter instead of directly wiring the source to the transmitting coil? What is the purpose of this? Apparently it increases efficiency and whatnot but any theory behind this is appreciated.
