The system which enhances wireless power transmission e-ciency for bio-medical applications has been proposed in this report. The system that operates at giga-hertz ranges is based on an inductive coupling between a transmitter coil and a receiver coil. A magnetic current source was modeled to a magnetic dipole with magnetic dipole moment m. To increase wireless power transmission e-ciency, a high surface impedance ground plane was used and re∞ection from the ground plane is responsible for constructive interference. For this system, a theoretical study has been performed in this report by solving Sommerfeld integrals. Compared with the result of a system without a ground plane, the system with a high surface impedance ground plane showed enhancement of received power at a given transmitted power.
