Abstract

I will discuss recent development of hierarchical fabrication techniques for three-dimensional plasmonic metamaterials in optical frequencies based on electron-beam lithography overlay. Also, the recent effort of bottom-up approach using nanoparticles and self-assembled materials for isotropic 3D metamaterials will be discussed. Such unique fabrication techniques will provide the opportunity to achieve true isotropic metamaterials.
