Abstract

Transformation optics^1-5 uses the fact⁵ that optical media alter the geometry of space and time for light. A transformation medium performs an active coordinate transformation: electromagnetism in physical space, including the effect of the medium, is equivalent to electromagnetism in transformed coordinates where space appears to be empty. Some of the most striking applications of transformation optics include invisibility ^1,2,4 or perfect lensing based on negative refraction.⁵ Here we discuss an idea for a superantenna based on coordinate transformations. This device is invisible for most of the rays while it condenses others into a single point. Our device relies on a three-dimensional extension of optical conformal mapping ^2,3 as we describe below.
