Fabrication of three dimensional split ring resonators by stress-driven assembly method

This paper demonstrates a self-assembly strategy for fabricating three dim ensional (3D) metamaterials. This strategy represents the desired 3D curving prongs of the split ring resonators (SRRs) erected by metal stress force with appropriate thin film parameters. Transmittance spectra and field distribution corresponding to each resonance modes are calculated by finite element method (FEM). The eigen-modes of the SRRs can be excited by normal illuminati on with polarization state parallel to the erected SRRs, which are unlike for the cases of planar SRR s . This method opens a promising fabrication process for the application of tailored 3D SRRs .
