Wireless Power Transfer (WPT) is an option to gain mobility and convenience while charging electrical devices. Metamaterials are used to increase the energy transmission efficiency by coupled magnetic resonance. A WPT system was implemented in a 3D electromagnetic solver, where three configurations were simulated: initially without Metamaterials, with Split Ring Resonators, and with a superconductor spiral line (superconducting Metamaterials) that was designed in this work. An investigation of the power and efficiency of these systems was carried out through simulations. The distance between the coils was increased from 4 until 10 cm, and the horizontal misalignment varied up to 3 cm. The metamaterials showed themselves efficient as can be seen in the results.
