Design of hybrid narrow-band plasmonic absorber based on chalcogenide phase change material in the infrared spectrum

Abstract Structures absorbing electromagnetic waves in the infrared spectral region are important optical components in key areas such as biosensors, infrared images, thermal emitters, and special attention is required for reconfigurable devices. We propose a three-dimensional metal-dielectric plasm...
