We calculate >13-fold enhancement in a 7.5 nm thin-film absorber yielding a maximum absorption of 74.4%. Broadband and wide-angle absorption is demonstrated.Keywords: Near-field enhancement; Plasmonic; Resonance absorption; Ultra-thin; Wide-angle absorption; Plasmons; Photonics201210.1109/IPCon.2012.63584852016-02-24
