METHOD AND SYSTEM WITH FRAGMENTED METASTRUCTURES FORMED WITH A PLURALITY OF METASURFACE ARRAYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18577913 titled 'METHOD AND SYSTEM WITH FRAGMENTED METASTRUCTURES FORMED WITH A PLURALITY OF METASURFACE ARRAYS
The abstract describes a method and system involving retroreflective metastructures made up of multiple metasurface arrays that cancel out or interfere with each other to reduce scattering or reflection.
- Retroreflective metastructures are formed using metasurfaces with different lattice spacings.
- These structures can enhance bandwidth and angular range at near-grazing angles.
- The goal is to improve retroreflective electromagnetic responses.
Potential Applications: - Enhanced retroreflective surfaces for road signs and safety gear. - Improved visibility in low-light conditions for vehicles and pedestrians. - Enhanced communication systems for military or aerospace applications.
Problems Solved: - Reducing specular mode scattering or reflection. - Enhancing retroreflective responses at various angles.
Benefits: - Increased safety and visibility in various applications. - Improved communication and signal strength in critical scenarios.
Commercial Applications: Title: Advanced Retroreflective Metastructures for Enhanced Visibility and Communication This technology could be used in road safety equipment, military communication systems, and aerospace applications, among others.
Questions about Retroreflective Metastructures: 1. How do retroreflective metastructures improve visibility in low-light conditions?
- Retroreflective metastructures enhance visibility by reducing scattering and reflection, making objects more visible even in challenging lighting situations.
2. What are the potential commercial applications of retroreflective metastructures?

Original Abstract Submitted
An exemplary method and system are disclosed comprising retroreflective metastructures formed with a plurality of metasurface arrays configured to destructively cancel or interfere, in part, with one another to reduce specular mode associated scattering or reflection. In some embodiments, the retroreflective metastructures are formed by a combination of metasurfaces with different lattice spacings that can exhibit enhanced bandwidth and angular range at near-grazing angles to provide enhanced retroreflective electromagnetic responses.
