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.
Abstract:
Provided is a bulk acoustic resonator (BAR)-based resonant structure in relation to electric and radio technologies, and more particularly, to a wireless power transmission system. A resonant apparatus for wireless power transmission may include a conducting loop, and a high quality capacitor. The high quality capacitor may include a metacapacitor including a thin piezoelectric layer disposed between two metal electrodes. The metacapacitor may be disposed between two dielectric layers of which central portions are etched, and the conducting loop may be disposed on an upper layer of the two dielectric layers.
