Abstract
Bilayers comprising two matched layers of dielectric thin-film helicoidal bianisotropic mediums (TFHBMs) with opposite structural handedness reflect arbitrarily polarized, normally incident, plane waves almost perfectly in a certain frequency range. As TFHBMs are porous, a model is devised to show that the infiltration of a TFHBM bilayer by a gas can shift as well as reduce the span of this range. Accordingly, a suitably designed TFHBM bilayer can serve as the active element of an optical device for sensing gas concentration.
