Trans-scale hierarchical metasurfaces for multispectral compatible regulation of lasers, infrared light, and microwaves.

ABSTRACT: Electromagnetic scattering control of optical windows has significant challenges in improving optical transmission and compatibility, especially for multispectral and large-angle incidences, due to material and structure mismatches. This paper presents trans-scale hierarchical metasurfaces (THM) to achieve wide-angle optical transmission enhancement and electromagnetic scattering-compatible regulation in dual-band lasers, and infrared and microwave ranges. THM comprises an ultrafine hollow metal array (UHMA) and a transmission-enhanced micro-nanocone array (TMCA). The UHMA regulates microwave radar cross-section (RCS) echo diffuse reflection, while the upper-layer TMCA enables wide-angle optical transmission enhancement. A THM sample of 200 × 200 mm² was fabricated using multist
