Abstract
Materials with broadband ultralow optical reflectivity are useful for applications in diverse fields including defense, energy, and imaging. We experimentally demonstrate dual-scale surfaces comprising nm- and µm-scale features with measured total reflectivity less than 3% from 400 to 2000 nm.
