Abstract

AbstractIn the present study, we first demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and visible band. Then, we numerically demonstrate a configuration for the enhancement of power passing through an electrically small hole. By using deep subwavelength optical split ring resonator antennas and couplers we achieved a 400‐fold enhanced transmission from a subwavelength aperture area of the electrical size λ2/25. The power was transmitted to the far field with 3.9 dBi directivity at 300 THz. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
