A Three-Dimensional Dual-Band Terahertz Perfect Absorber as a Highly Sensitive Sensor
Terahertz (THz) absorbers are highly desirable in sensing and detection devices. Herein, we have proposed a 3D dual-band near-perfect absorber that works in the THz regime for sensing applications. The theoretical calculation shows that the absorption efficiency of the absorber can reach 99.0 and 97...
