Abstract
Provided is a self-resonant apparatus in relation to electric and radio technologies, and more particularly, to a wireless power transmission system, the self-resonant apparatus including ring resonators. Here, the ring resonators may be represented by a combination having metamaterial features, the combination may include split-ring resonators (SRRs) connected in parallel to capacitors, a front surface and a rear surface of each of the SRRs may be connected to be twisted in an alternating pattern, and each SRR may be executed as a metal strip mounted on a dielectric layer and connected to a neighboring SRR by a series capacitor.
