A study of waveguide structures with magnetic walls that were based on mushroom-shaped metamaterials has been carried out. We used Ansoft HFSS to simulate waveguide filters with a forbidden frequency band. The results obtained showed that a magnetic wall made of periodic various sized unit cells can provide several forbidden frequency bands instead of only one in case of single sized elements. We also demonstrated that it is possible to control rejection bands of frequency-selective surfaces by varying the permeability of ferrite coating of the metamaterial.
