Not Accessible

Your library or personal account may give you access

Abstract

Here we report a metal-insulator-metal based infrared plasmonic metamaterial absorber consisting of deep subwavelength meander line nanoantennas. High absorption from 11 μm to 14 μm is experimentally demonstrated with a pixel pitch of 1.47 μm.
