Analysis of wireless power transmission between metamaterial-inspired loops

This paper models and analyzes the wireless power transmission (WPT) between two metamaterial-inspired loops employing a generalized equivalent circuit. The use of the metamaterial-inspired loop is for uniform current distribution along the loop even when the loop circumference is comparable to wavelength. This paper also provides extraction methods of all the necessary circuit parameters related with WPT based on EM simulations or measurements. The mechanism of WPT, including that of radiation loss, is clearly explained with adequate formulations.
