Spectral problem for the chains of weakly coupled conglobate resonators

In this paper we consider the spectral problem for two kinds of chains of weakly coupled conglobate resonators: a direct one and one with a kink. Equations for spectrum of these chains are derived by using of the theory of self-adjoint extensions of symmetric operators, Bloch's theory and approach of the transfer-matrices. The paper shows that the system of direct-type chain of weakly coupled conglobate resonators has a continious energy spectrum with a band structure. And for the chain with a kink we prove the existence of point spectrum.
