摘要

光学响应函数的有理近似照明元表面的光学响应可以用激励频率的有理函数进行局部近似，其极点位于复值共振频率处。Felix Binkowski 及其合作者扩展了 AAA 算法（一种有理近似方法），额外提供了共振模式和灵敏度，这对于元表面设计和优化非常重要（见文章编号 2400584）。

Efficient Rational Approximation of Optical Response Functions with the AAA Algorithm (Laser Photonics Rev. 18(11)/2024)

Rational Approximation of Optical Response Functions

The optical response of an illuminated metasurface can be approximated locally by a rational function of the excitation frequency with poles at the complex-valued resonance frequencies. Felix Binkowski and co-workers extend the AAA algorithm, a method for rational approximation, to additionally provide resonance modes and sensitivities, which are important for metasurface design and optimization (see article number 2400584).
