Giant Gyrotropy due to Electromagnetic-Field Coupling in a Bilayered Chiral Structure
Giant Gyrotropy due to Electromagnetic-Field Coupling in a Bilayered Chiral Structure
We report experimental evidence that electromagnetic coupling between physically separated planar metal patterns located in parallel planes provides for extremely strong polarization rotatory power if one pattern is twisted with respect to the other, creating a chiral object. In terms of a rotary power per sample thickness equal to one …
