摘要

复杂的非局部行为使设计高效多功能元表面成为一项重大挑战。虽然使用元原子库提供了一种简单快速的实现方法,但支柱与支柱之间的相互作用往往会带来性能限制。另一个极端是,基于拓扑优化的反向设计可利用非局部耦合实现高效率,但会导致结构复杂且难以制造。在本文中,我们通过数值和实验证明了一种形状优化方法,它能实现高效率的元表面,同时通过表面梯度的傅立叶分解直接控制结构的复杂性。所提出的方法为实现反向设计的高效率元表面的可制造性提供了一条途径。

Shape optimization for high efficiency metasurfaces: theory and implementation

Complex non-local behavior makes designing high efficiency and multifunctional metasurfaces a significant challenge. While using libraries of meta-atoms provide a simple and fast implementation methodology, pillar to pillar interaction often imposes performance limitations. On the other extreme, inverse design based on topology optimization leverages non-local coupling to achieve high efficiency, but leads to complex and difficult to fabricate structures. In this paper, we demonstrate numerically and experimentally a shape optimization method that enables high efficiency metasurfaces while providing direct control of the structure complexity through a Fourier decomposition of the surface gradient. The proposed method provides a path towards manufacturability of inverse-designed high efficiency metasurfaces.
