\begin{abstract}
In the last few years a set of reports about experimental study of spin-wave propagation in confined ferromagnetic structures were published [1,2]. Authors pointed out that some observed effects and dependences cannot be described in the frames of commonly used analytical approach.  In this work, with the help of recently elaborated theory [3], we explain several experimental cases appeared in literature which concerned with the different finite-width structures: regular magnonic waveguide, waveguide with variable width, waveguide with periodically modulated width. We show the evidence of localized states appeared in spin-wave spectrum of the confined structures and describe their frequency dependence on the external magnetic field and the parameters of the structure.
