We present a novel approach of antireflection coating using metamaterials. It dramatically reduces the reflection and greatly enhances the transmission near a specifically designed frequency over a wide range of incidence angles for both transverse magnetic and transverse electric polarizations. A classical interference mechanism is identified through analytical derivations and numerical simulations. It elucidates that the tailored magnitude and phase of waves reflected and transmitted at boundaries of metamaterial coating are responsible for the antireflection.
我们提出了一种使用超材料的新型抗反射涂层方法。通过分析推导和数值模拟，确定了一种经典的干涉机制。该机制表明，超材料涂层边界处反射和透射波的幅度和相位的精心设计是实现抗反射的原因。该方法在宽入射角范围内，显著降低了横向磁场和横向电场两种偏振光在特定设计频率附近的反射率，大大提高了透过率。
