摘　　要：Brewster效应作为一种经典物理现象描述了平面偏振电磁波在电介质表面上的零反射行为。随着超材料和超表面的迅速发展,Brewster效应得到了许多扩展研究。人们借助超材料和超表面实现了任意频率、偏振和入射角的平面电磁波的零反射现象,这被称为广义Brewster效应。本文综述了广义Brewster效应的物理实现及其应用研究,首先回顾了实现广义Brewster效应的各种物理体系和物理机制,指出了一些传统分析方法的局限性。为此,创新性地讨论了广义Kerker效应的一种简单而普适的设计原则,即通过人工结构构建多极矩的干涉相消。随后,回顾了在该原则指导下设计的各种超表面,进一步讨论了其在5G毫米波通信电磁窗口和相控阵天线宽角扫描的应用。最后指出了这一领域目前存在的问题并展望了未来的发展方向。Significance As a classical physical phenomenon,the Brewster effect describes the zero-reflection behavior of a polarized planar electromagnetic wave impinging on the surface of a linear homogeneous isotropic non-magnetic media.Traditionally,this classical effect is usually restricted to particular incident angle and polarization due to the scarcity of natural material with ideal magnetic response,and the research on generalizing the classical Brewster effect was only of theoretical interest.Nevertheless,the advent of metamaterials and metasurfaces brings new vitality to the research field of the so-called generalized Brewster effect(GBE),where many efforts have been done for seeking zero-reflection of planar wave at any frequency,any polarization and any incident angle.The physical implementation of GBE has enabled people to gain a greater degree of freedom for modulating electromagnetic waves in a wide range of frequency,polarization and angle of incidence.Therefore,the GBE has been demonstrated to have important applications in many fields such as wireless communications,phased array antennas,nanophotonics and even chemical sensing.So far,both physical mechanisms and experimental methods of GBE have been explored in a variety of physical systems.Many theoretical methods for explaining the GBE mechanism have been proposed,such as optical filter theory,transfer matrix method,molecular optics method and so on.However,most of these methods are either lack of intuitive physical understanding or only applicable to specific physical scenes,and thus cannot provide useful guidelines for GBE design.Moreover,in the past research,the realized GBEs are often fixed at some frequencies or incident angles and untunable,limiting their application in varied situations.Hence,a universal and intuitive GBE design principle is highly demanded,and it is important to summarize the existing research on both the general design method and arbitrarily tunable GBE realization.Furthermore,the application aspect of GBE is rarely discussed i
