Abstract
Conference Title: 2015 IEEE Photonics Conference (IPC) Conference Start Date: 2015, Oct. 4 Conference End Date: 2015, Oct. 8 Conference Location: Reston, VA, USA We differentiate the spacer-dependent peak shift in coupled and decoupled super absorbing metasurfaces based on magnetic resonance and interference mechanism, respectively, which was experimentally validated by low-cost structures fabricated by lithography-free processes.
