Stop bands that are either weakly or strongly controllable can be exhibited by a single metasurface by proper choice of the orientation of the magnetostatic field, and a ∼19%downshift of stop bands in the 0.1-5.5 THz spectral regime is possible on increasing the magnetostatic field strength from 0 to 1 T. Better controllability and wider bandwidths are possible by increasing the number of metasurfaces in a cascade, although increase of the total losses can lead to some restrictions. ON/OFF switching regimes, realizable either by applying/removing the magnetostatic field or just by changing its orientation, exist.EnglishBandpass filtersTerahertz wavesLinearly polarizedMagnetostatic fieldMetasurfaceMetasurfacesResonating elementsSub-wavelengthTera hertzTerahertz filtersMagnetostaticsArticle10.1364/JOSAB.33.000834
