The electromagnetic wave receiver designed according to the present invention receives the electromagnetic wave time-varying magnetic field generated by the electromagnetic wave generator using the induction coil (L1) and connects the variable capacitor (C1) in parallel with the induction coil (L1) to form a resonance circuit. Therefore, the received power is maximized to drive the LEDs and the display panels that are the loads. When the distance between the electromagnetic wave generator and the electromagnetic wave receiver is a little far away, the electromagnetic amplification repeater for amplifying the electromagnetic wave may be installed in the intermediate position to greatly increase the conversion power received by the receiver. The electromagnetic amplification repeater is composed of an induction coil and a variable capacitor, and more detailed technical information is described in detail in 10-2004-0093696 filed in 2004 by the inventor of the present invention.
