A Cascade Scheme for Effectively Realizing Plasmonic-induced Absorption and Its Applications in Refractive Index Sensing

摘要

In this paper, we design a simple plasmonic structure for effectively realizing plasmonic-induced absorption (PIA). It's core part only includes two parallel rectangular cavities. On this basis, we propose a cascade structure, aforementioned dual-rectangular cavity system used as building block, to further improve fast-light transmission.
