Broadband silicon-based tunable metamaterial microfluidic sensor
文献摘要：
Tunable metamaterial absorbers play an important role in terahertz imaging and detection.We propose a multi-functional metamaterial absorber based on doped silicon.By introducing resonance and impedance matching into the absorber,a broadband absorption greater than 90％in the range of 0.8-10 THz is achieved.At the same time,the light regulation characteristics of the doped semiconductor are introduced into the absorber,and the precise amplitude control can be achieved in the range of 0.1-1.2 THz by changing the pump luminous flux.In addition,based on the principle of light-regulating the concentration of doped silicon carriers,the medium-doped silicon material is replaced by a highly doped silicon material,and a sensor with a sensitivity of up to 500 GHz/RIU is realized by combining the wave absorber with the microfluidic control.Finally,the broadband absorption char-acteristics and sensing performance of alcohol and water on the prepared device are verified by experiments,indicating that the absorber may have great potential in the field of sensor detection.
