Fabrication of Multiple 3D Ring Resonators by FDTD Method

Abstract

This paper presents Multiple split ring resonator (MSRR) by suppressing the electric dipole moment approach. To tremendously reduce the loss, the loss mechanism of the MSRR is theoretically analyzed in detail. The non uniform current distribution on the SRR loop results in the residual electric dipole moment and thus brings the high radiation losses. Three different SRR configurations that the lumped capacitor, the distributed capacitor and the dielectric medium are incorporated into the SRR meta material are conceived, by which the uniform current distribution can be observed. We demonstrate a self-assembly strategy for fabricating three dimensional (3D) meta materials. A high-spatial-order scheme of the finite-difference time-domain (FDTD) method has been applied to the three-dimensional (3D) full wave analysis of optical dielectric rib-waveguide circuits such as ring resonator filters. The eigen-modes of the SRRs can be excited by normal illumination with polarization state parallel to the erected SRRs
