Multi-Objective Optimization of 2.5D and 3D Meta-Atoms

Metamaterial and metasurface devices (i.e., meta-devices) have shown tremendous potential for disrupting conventional RF and optical components due to their ability to manipulate the propagation of electromagnetic waves in a tailored fashion. These meta-devices are generally synthesized from building blocks known as “meta-atoms” whose properties are engineered to achieve a specific electromagnetic response. In order to maximize the performance of these meta-atoms, numerical optimization techniques are often employed in conjunction with rigorous full-wave electromagnetics solvers due to their complex behaviors and the lack of established design rules. In this presentation, inverse-design strategies based on multi-objective optimization are introduced and used to realize high performance 2.5D and 3D meta-atom building blocks which can be used to synthesize a variety of meta-devices.
