The quarter-wavelength matching technique is widely used because it minimizes the reflection while it maximizes the transmission. The recently introduced antireflection temporal coatings (ATCs) [Optica 7, 323 (2020) [CrossRef] ] have been considered as its temporal analog. However, our study shows that by introducing an ATC, not only will the reflection be reduced but also the transmission. This phenomenon is opposite its spatial counterpart, which indicates that ATCs are more than simply a temporal dual of quarter-wavelength matching. This is a direct consequence of the different physical phenomena that are manifested in the temporal and spatial domains.

抗反射时间涂层：评论

四分之一波长匹配技术被广泛使用，因为它最大限度地减少了反射，同时最大限度地提高了透射率。最近推出的抗反射时间涂层 (ATC) [Optica 7 , 323 (2020) [CrossRef] ] 已被视为其时间类似物。然而，我们的研究表明，通过引入 ATC，不仅会减少反射，还会减少传输。这种现象与其空间对应物相反，这表明 ATC 不仅仅是四分之一波长匹配的时间对偶。这是在时间和空间域中表现出来的不同物理现象的直接结果。
