1. A method for creating metadevices, the method comprising:
receiving, at a computing device, a desired output electromagnetic field distribution for a metadevice;
determining, with an inverse-design algorithm stored in a memory of the computing device, an electric field and a dielectric permittivity for a metadevice structure design that satisfies the desired output electromagnetic field distribution;
converting, by a processor of the computing device, the metadevice structure design into a file that is compatible with an additive manufacturing device;
providing the file of the metadevice structure design to the additive manufacturing device; and
creating, by the additive manufacturing device, the metadevice that satisfies the desired output electromagnetic field distribution.
