Terahertz (THz) plasmonic sensors has been regarded as exciting advances in biomedical engineering, due to their real-time, label-free, and ultrasensitive monitoring features. But actually, its widespread application remains impeded by poor modulation pr
Graphene, a two-dimensional carbon material, stands out for terahertz applications with broadband absorption, ultrafast response time, and tunability. This study presents two model graphene-based THz absorbers, designed and simulated using finite element method (FEM). The first model, in the mid-...
In this paper, a tunable broadband metamaterial absorber (MA) based on graphene is investigated theoretically and numerically at mid-infrared regions. Compared with the previously reported multiband graphene-based MAs, a broad bandwidth of 11.7 THz wi
For measurements with longer wavelength photo-sources (e.g. MMW ~ THz), the scan interval can range from sub-mm to a few mm, longer than the target wavelengths and the scan speed could be up to a few cm/s. Operation of the reflective multi-view stereoscopic capsule PTE imager The...
