Electrodynamic characteristics of microwave filters on spherical resonators with volumetric inhomogeneous metal-dielectric filling are investigated numerically. Two options of the design of band-pass filters for different frequency ranges are considered. Classification of several lowest modes excited in spherical resonator with metal core and additional annular element is proposed.
