All-nickel Metamaterial Narrow-band Absorber for Mid-IR Gas Sensing

Not Accessible

Your library or personal account may give you access

Abstract

We propose an all-metal metamaterial narrow-band perfect absorber using nickel and working in the mid-infrared. Peak absorption of 99.9% is achieved with the absorption bandwidth reaching to 4 nm and Q factor higher than 1033.
