Abstract
Broadband metamaterial apparatus, methods, systems, and computer readable media are disclosed, as well as exemplary embodiments that provide cloaking, beam steering, and beam focusing. In one exemplary implementation, a broadband interface structure has a front surface region and a back surface region. The broadband interface structure is arranged to provide electromagnetic energy characteristic of an apparent profile of the back surface region substantially different than an actual profile of the back surface region for electromagnetic energy received at the front surface region.
