摘要

广义薄片跃迁条件(GSTCs)最近被用于合成以任意方式变换特定单色入射波的超表面。本文将该技术推广到一般的多色设计中。由此产生的多色超表面对入射脉冲电磁波的时间和空间频率成分提供了前所未有的控制。它们可以在空间滤波器、空间相位器、实时傅立叶变压器和实时频谱分析仪中找到应用。

Exact polychromatic metasurface design: The GSTC approach

The generalized sheet transition conditions (GSTCs) have been recently leveraged for synthesizing metasurfaces transforming specified monochromatic incident waves in arbitrary fashions. This paper extends the technique to general polychromatic designs. The resulting polychromatic metasurfaces provide unprecedented control on the temporal and spatial frequency components of incident pulsed electromagnetic waves. They may find applications in spatial filters, spatial phasers, real-time Fourier transformers and real-time spectrum analyzers.
