Abstract
Various embodiments comprise systems, methods, mechanisms, apparatus, and improvements thereof providing a machine learning based inverse design method for electromagnetic structures by specifying an electromagnetic structure design goal including a target electromagnetic response; representing a physical structure of an electromagnetic structure as an array of pixels, wherein each pixel indicates the presence or absence of conductive material wherein the represented physical structure of the electromagnetic structure further includes one or more input ports on one edge of the array and one output port on another edge of the array; providing a neural network (NN) based electromagnetic (EM) emulator configured to predict scattering parameters of electromagnetic structures represented by the array of pixels over frequencies of interest; and optimizing, using the NN-based EM emulator, across a multi-dimensional design space of possible electromagnetic structure representations using evolution algorithms until an electromagnetic structure substantially satisfying the electromagnetic structure design goal is reached.
