Evolutionary Structural Optimization Algorithm Based on FFT-JVIE Solver for Inverse Design of Wave Devices

We propose a topology optimization method with a target function based on FFT-JVIE solver. It allows to find an optimal structure in a 3D space for homogeneous objects (lenses and metallic reflectors). Such examples as glass lenses, parabolic reflectors are considered. Numerical experiments show that discrete gradient algorithm converges much faster than greedy algorithm for all considered cases.
