The theory of refraction of exchange spin waves in inhomogeneous ferromagnetic structures of spin lens type with inhomogeneous interfaces is constructed. For a number of spin lens configurations, the possibility of effective control of the spin wave intensity, as well as adjusting the transparency of such inhomogeneities is shown, which allows to use them both as lenses and as mirrors depending on the external field and wave frequency. Comparative characteristics of the reflectivity of spherical and cylindrical surfaces of spin lenses are given. The spectral characteristics of spin waves in one-, two-, and three-dimensional magnon crystals and other inhomogeneous ferromagnetic nanostructures have been calculated.
