Disclosed here are a method of marking a dark-colored surface with a dark-colored LiDAR-reflective material and a marking composition comprising the dark-colored LiDAR-reflective material and a marking carrier. Particularly, the dark-colored LiDAR-reflective material comprises has a reflectivity in the visible spectrum of electromagnetic radiation that is ≤10% and a reflectivity in the near-IR and LiDAR spectrum of electromagnetic radiation that is ≥10%.

Lidar reflective material and marking system

An actuator can include an outer body. At least a portion of the outer body can be configured to pivot. The actuator can include a contracting member, such as a shape memory material member. When an activation input is provided to the contracting member, the contracting member can contract. As a result, the actuator can be caused to morph into an activated configuration in which a dimension, such as the height, of the actuator increases.

A metamaterial comprises a support medium, such as a planar dielectric substrate and a plurality of resonant circuits supported thereby. At least one resonant circuit is a tunable resonant circuit including a conducting pattern and a tunable material, so that an electromagnetic parameter (such as resonance frequency) may be adjusted using an electrical control signal applied to the tunable material.
