Not Accessible

Your library or personal account may give you access

Abstract

Novel Micro-to-Nano scalable plasmonic flat horn antenna was proposed. A 2.2µm high antenna collected 152µm2 to 52µm2 with 72% efficiency for λ=1550nm. For 1µm to 10nm collection, a resonant 50,000-fold enhancement in absorption was achieved.
