Fast fabrication of silver helical metamaterial with single-exposure femtosecond laser photoreduction
Metallic helical metamaterials have become the prominent candidates for circular polarizers and other optical-chiral devices as they exhibit strong circular dichroism at a broad operation bandwidth. However, the rapid fabrication of an intertwined double helix with multiple pitch numbers and excelle...
