Abstract: Provided are new classes of reconfigurable, multistable metasurfaces using the physics of colloids confined within nematic liquid crystals (NLCs). The colloids are physically moved from one stable location to another as defined by NLC-colloid interactions by external switching fields. These colloids can be scatterers within reconfigurable metasurfaces with electromagnetic (EM) responses that change with colloid location. because the colloids are moved between stable loci, these metasurfaces are also multistable, and require energy input only when changing colloid position. Furthermore, because the colloids can be returned to their original positions by simply reversing the switching field, all changes in EM responses are entirely reversible.
