Abstract :
We report on a novel sensing method in the terahertz (THz) range using thin metallic mesh (TMM). Conventionally, the filter property of a TMM can be changed by the geometrical parameters of the TMM. Considering that it is also change when the medium in the vicinity of the mesh openings has a different refractive index, we inspected this principle. For the biomaterial measurements, we deposited the avidin solution uniformly on the TMM. We observed the change of the transmission characteristics.
