Patent ID: 8598744

Claim:
An apparatus for transmitting and receiving wireless energy using meta-material structures having a negative refractive index, comprising: a wireless energy transmission unit for, when external power is applied thereto, generating wireless energy to be wirelessly transmitted, and then wirelessly transmitting wireless energy, which is normally propagated radially when the generated wireless energy is transmitted, using a magnetic resonance method while concentrating the wireless energy at a single point; and a wireless energy reception unit for wirelessly receiving the wireless energy, transmitted by the wireless energy transmission unit, using the magnetic resonance method while concentrating the wireless energy at a single point, wherein the wireless energy transmission unit comprises: a wireless transmission loop configured to, when external power is applied thereto, generate the wireless energy using a resonance frequency based on an inductor and a capacitor and then wirelessly transmit the generated wireless energy using the magnetic resonance method; and a wireless transmission meta-material structure placed in a wireless transmission path, and configured to have a negative refractive index so as to transmit the wireless energy, which is normally propagated radially when the generated wireless energy is transmitted, while concentrating the wireless energy at a single point, wherein the wireless transmission meta-material structure is a meta-material structure which has a negative refractive index and which comprises meta cells periodically arranged and configured in a flat board form, each of the meta cells including a regular polygonal substrate and single split ring resonance patterns formed on respective surfaces of the regular polygonal substrate, wherein gaps of the single split ring resonance patterns, formed on opposite faces of the regular polygonal substrate of the meta cell, are directed in an identical direction.
