Abstract

Embodiments of the present disclosure relate to a programmable metamaterial which comprises an array of phase-change material elements. A domain inducing component may be coupled to at least one phase-change material element of the array of phase-change material elements. The domain inducing component may be configured to program the refractive index of the at least one phase-change material element and reprogram the refractive index of the at least one phase-change material element by inducing a phase transition in a domain of the at least one phase-change material element. A method for programming the metamaterial may include selecting the phase-change material element for programming and programming the refractive index of the selected phase-change material element by inducing a phase transition in a domain of the selected phase-change material element.
