Inverse Design of Multi-Input Multi-Output 2-D Metastructured Devices

In this work, an optimization-based inverse-design method is provided for multi-input–multioutput (MIMO) metastructured devices. Typically, methods use a full-wave solver in conjunction with optimization routine to design Due the computational cost, approach not practical designing electrically large aperiodic To address issue, 2-D circuit network using reduced-order models of metastructure’s unit cells introduced. The used gradient-based that uses adjoint variable solve large-scale problems such as those posed by validate method, planar beamformer and analog signal processor aperture field reconstruction are designed validated simulations.
