Abstract
We propose using frequency selective surfaces as resonant sensors for simultaneous measurement of several optical properties of thick films placed in contact with a flat part of the device. Changes in refractive index, losses and thickness of a film can be measured by detecting changes in the spectral position, and amplitude of the transmission peaks in the THz fiber spectrum. As an example, our simulations show 0.16 GHz / μm sensitivity to changes in the film thickness.
