A multichannel sensor for parameters of layered media with one detective element

We propose detective element structures for a multichannel sensor based on a distributed long line with kinks distributed along its length. We find generalized relations between the eigenvalues of a resonator with an arbitrary number of kinks and the parameters of layered media with an arbitrary number of layers in order to form control systems from which, having measured the eigenfrequencies, we can find the positions of layer boundaries and their dielectric permittivity. We study structures and algorithms that ensure uniqueness of the solution for these systems in two‐ and three‐layered media.
