Abstract

Results of analysis of correctness and limitations of the classical Coupled Cavity Model are presented in the paper. It is shown that in the case of an infinite chain of resonators, there are spurious solutions of the characteristic equation. These spurious solutions do not violate the correctness of direct numerical calculations, but their existence makes it difficult (or even impossible) to use approximate WKB methods for analyzing chains with slowly varying parameters.
