This article proposes an alternative method for designing miniature waveguide filters based on locally resonant metamaterials. Implementation of ultra-small metamaterial filters (metafilters) using the subwavelength direction mechanism in hollow waveguides loaded with small resonators. In particular, composite pin waveguides are used, constructed from a hollow metal tube loaded with a set of resonant pins that are spaced over deep subwavelength distances. In such structures, multiple resonance scattering leads to the emergence of a sub-λ mode with a tunable bandwidth below the induced hybridization gap. In order to guarantee compatibility with existing technologies, a subwavelength method of matching small filters with standard waveguide interfaces, which can be called a metaport, is proposed. Calculations were performed using the CST Studio computeraided design environment.
