Microelectromechanical systems bimaterial terahertz sensor with integrated metamaterial absorber
Alves_Microelectro.pdf (307.8Kb)Abstract
This Letter describes the fabrication of a microelectromechanical systems (MEMS) bimaterial terahertz (THz) sensor
operating at 3.8 THz. The incident THz radiation is absorbed by a metamaterial structure integrated with the bimaterial.
The absorber was designed with a resonant frequency matching the quantum cascade laser illumination
source while simultaneously providing structural support, desired thermomechanical properties and optical readout
access. Measurement showed that the fabricated absorber has nearly 90% absorption at 3.8 THz...
