  2. Metamaterial analog computing is a concept that uses metamaterial blocks to perform mathematical operations on the profile of an impinging wave1. Metamaterials provide a platform to leverage optical signals for performing specific-purpose computational tasks with ultra-fast speeds234. They offer a powerful platform for building analog optical computers3. Metamaterials and metasurfaces with freely controlled optical properties have accelerated the progress of wave-based analog computing and are emerging as a practical, easy-integration platform for optical analog computing4.

    We introduce the concept of metamaterial analog computing, based on suitably designed metamaterial blocks that can perform mathematical operations (such as spatial differentiation, integration, or convolution) on the profile of an impinging wave as it propagates through these blocks.

    Are metamaterial-based optical computers better than conventional computers?Metamaterial-based analog optical computers may one day perform certain tasks much faster and with less power than conventional computers, says Engheta. Metamaterials are synthetic materials made by assembling many units that are each smaller than the wavelength of the light they are designed to manipulate.
