A comprehensive study on metallic nano-hole arrays with a surface plasmon energy matching property

摘要

A metallic nano-hole array (NHA) structure with dynamic SP energy matching has been recently introduced, which benefits from a smaller resonance bandwidth, higher resonance transmission efficiency, and higher surface plasmon resonance (SPR) sensitivity compared to a structure without dynamic SP energy matching. Here, we present a more comprehensive study on the effects of SP energy matching on SPR sensitivity of a NHA structure by numerical and experimental means. Both experimental and numerical results were analyzed and compared and demonstrated that structures with dynamic SP energy matching had improved sensitivity over structures without the dynamic SP energy matching property.
