A Wireless Power Transfer system consists of a transmitter coil which is inductively coupled with secondary coil and is popular for wireless charging of future office communication system. Wireless power transfer is used in different applications ranging from mobile chargers to charging stations. In this paper simulation of Wireless Power Transfer for future office communication systems has been conducted over Maxwell 3d of Ansys electromagnetic suite. The input frequency of primary coil is varied from 1kHz -120kHz with respect to the change in resonant capacitance and observed that input frequency between 20kHz-30 kHz, the output power in secondary coil appears to be maximum at variable distances between transmitter coil and receiver coil. There is an improvement of 72% seen in the output power of secondary coil for 25kHz input frequency of primary coil as compared with 40kHz input frequency. This model can be helpful to design future Office Communication systems for charging the mobile phones, Laptops and to turn on the printer wirelessly.

Metamaterial (MTM) slabs, realized using Split Ring Resonators (SRR’s) to enhance efficiency of Wireless Power Transfer (WPT) systems is discussed here. A detailed study of intrinsic properties obtained by simulation of the actual MTM slab is presented. An improvement in the wavelength to unit cell size of 813, at a low operating frequency of 5680 kHz is shown. Forward transmission coefficients (S₂₁) for with and without MTM slab cases are compared. In this low frequency regime, with simulated S-parameters an efficiency of ~ 68% is achieved by placing the MTM slab closer to receiver coil than the transmitter coil.
