    "abstract": "We report the first experimental evidence that electromagnetic coupling\nbetween physically separated planar metal patterns located in parallel planes\nprovides for exceptionally strong polarization rotatory power if one pattern is\ntwisted in respect to the other, creating a 3D chiral object. In terms of\noptical rotary power per sample of thickness equal to one wavelength, the\nbi-layered structure rotates five orders of magnitude stronger than a\ngyrotropic crystal of quartz in the visible spectrum. We also saw a signature\nof negative refraction for circularly polarized waves propagating through the\nchiral slab.",
