ABSTRACT

It has been found experimentally that the liquid in container placed into the resonance region at the interface of the two photonic crystals may have a pronounced impact on the parameters of resonance peak of transmission coefficient. It was shown that different liquids have a variety of character of the dependences of the inverse Q-factor and the resonance frequency of the resonance peak versus the distance from the interface of the photonic crystals to the container with liquid. This dependence leads to one-to-one identification of such liquid. The experimental dependences for various concentrations of ethyl alcohol in water, for various drinks and water of different temperatures have been measured and analyzed. Thus, the ability of express analysis of liquids in a container by using a metamaterial based on two planar photonic crystals has been demonstrated experimentally.
