Description
Summary:The successful fabrication and experimental verification of a novel metamaterial based on flexible metallic helices is reported. The helices undergo compression under the influence of incident radiation, demonstrating a nonlinear chiral electromagnetic response, associated with the power‐dependent change in the helix pitch. This design is promising for application to power‐dependent polarization rotation of propagating waves.
