Abstract

We report on a sensing method in the terahertz range using metallic mesh (MM). Conventionally, the filter property of an MM can be changed by the geometrical parameters of the MM. Considering that this property is also changed when the medium in the vicinity of the mesh openings has a different permittivity, we were able to measure small amounts of absorbing materials and thin plastic films on the metallic mesh. We observed change of both the transmission characteristics and the images.
