In this letter, a switchable frequency selective surface (FSS) based on the rotatable magnet is first proposed for polarization selector. The unit cell of the switchable FSS is composed of a rotatable cuboid‐magnet and a F4B substrate. The cuboid‐magnet is inserted into the substrate which controlled by the orthogonal dual‐U‐shaped electromagnetic control system. The FSS has a characteristic of polarization selectivity at 8.66 GHz by rotating the cuboid‐magnet. To confirm the simulation results, a prototype of the proposed FSS is fabricated and measured. The measured result shows that the switchable FSS can selective the passband in transverse‐electric polarization or transverse‐magnetic polarization.
