论文摘要
本文回顾了实现最大光学响应的材料属性。我们强调了理论上的结果，这些结果可以独立于形状的材料“功绩”量化，从经典总和规则到最近的单频散射范围。光频率下的关键描述是在支持高度下波长共振的极化材料和可能消失的损失率很小的介电材料之间。我们讨论了可以在这些材料类别和它们之间进行比较的关键指标。我们讨论了2D材料的类似指标，并指出了可以在批量和2D物质方法之间进行严格比较的应用。各种结果凸显了材料发现与理论纳米光子界限之间的协同作用，并指出了实现光线相互作用新极端的机会。
This article reviews the material properties that enable maximum optical response. We highlight theoretical results that enable shape-independent quantification of material "figures of merit," ranging from classical sum rules to more recent single-frequency scattering bounds. A key delineation at optical frequencies is between polaritonic materials that support highly subwavelength resonances and dielectric materials that can have vanishingly small loss rates. We discuss the key metrics that enable comparisons both within these material classes and between them. We discuss analogous metrics for 2D materials, and point to applications for which rigorous comparison can be made between bulk- and 2D-material approaches. The various results highlight the synergy between materials discovery and theoretical nanophotonic bounds, and point to opportunities in achieving new extremes in light--matter interactions.
