Abstract
A method for carrying out electromagnetic cloaking using metamaterial devices requiring anisotropic dielectric permittivity and magnetic permeability may be emulated by specially designed tapered waveguides. This approach leads to low-loss, broadband performance in the visible frequency range, which is difficult to achieve by other means. We apply this technique to electromagnetic cloaking. A broadband, two-dimensional, electromagnetic cloaking is demonstrated in the visible frequency range on a scale ˜100 times the wavelength. Surprisingly, the classic geometry of Newton rings is suited for an experimental demonstration of this effect.
