Abstract

We present the symphotic design method, a comprehensive variational approach suitable for designing large-scale electromagnetic metamaterial structures for desired sets of inputs and outputs. This approach provides self-consistent and efficient solutions by solving the inverse design problem under strong scattering limits within a dipole paradigm with relatively low computational complexity. We demonstrate its efficacy by designing non-perturbative symphotic media to generate two-dimensional quasi-Bessel beams for sources available at 10 GHz, and analyze the design and beam quality by varying available degrees of freedom.
