Abstract

Optical properties of a composite structure consisting of two sequentially arranged three-layer metal-dielectric-metal structures (MDM-structures) are considered. It is shown that such a composite MDM-structure can perform second-order spatiotemporal differentiation with high quality at normal incidence. The obtained results can find application in creating systems for analog optical computing and optical information processing.
