AB  - Metamaterials offer new propagation modes for electromagnetic signals which have been explored as media for data exchange. They also offer a good prospect for efficient power transfer. This paper considers the limits on transferable power and their consequences in relation to magneto inductive waves in 1 and 2 dimensional magnetic metamaterial structures. The upper limit is found to be directly related to the voltage tolerance of capacitances used in the meta-material’s construction. Higher resonant frequencies offer better efficiency and higher maximum powers. For a proposed device operating in the Qi band (100-200k Hz) power transfer limits of 140 W are derived. The effects of finite length guides on performance and limitations imposed by standing waves and improper termination are explored.
