Micropillar Templates for Dielectric Filled Metal Arrays and Flexible Metamaterials

Abstract

Arrays of holey metal films with dielectric or polaritonic micropillars filling or towering over the holes are prepared using templates from directionally solidified eutectics. The structures can be flexible and show localized enhanced optical transmittance and absorption induced transparency (AIT) in the near-infrared or THz ranges. This is the first time that AIT is experimentally demonstrated at THz frequencies. As a service to our authors and readers, this journal provides supporting information supplied by the authors. Such materials are peer reviewed and may be re-organized for online delivery, but are not copy-edited or typeset. Technical support issues arising from supporting information (other than missing files) should be addressed to the authors.
