QCN researchers have investigated numerically a two-dimensional SQUID metamaterial with and without quenched disorder and they have predicted multistability, which is a purely dynamic effect not related to the multistability known from hysteretic SQUIDs. These results show that SQUIDs can be used as fast, intrinsically switchable meta-atoms, for the construction of metamaterials with many potential applications, such as, for example, all-optical metamaterial switch.
