Extreme-angle broadband metamaterial lens
Nathan Kundtz,David R. Smith +1 more
TL;DR: It is demonstrated how powerful emerging techniques in the field of transformation optics can be used to harness the flexibility of gradient index materials for imaging applications to achieve a new class of optical devices.

Surface scattering antenna improvements
TL;DR: In this article, surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure, and the scattering elements are made adjustable by disposing an electrically adjustable material, such as a liquid crystal, in proximity to the scattering element.

TL;DR: In this article, surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure, where the scattering elements are complementary metamaterial elements.
Journal ArticleDOI
Optical lens compression via transformation optics
TL;DR: Though transformation optical media are generally anisotropic, with both electric and magnetic response, it is possible to arrive at a dielectric-only transformation optical distribution for a lens interacting with transverse-magnetic (TM) polarized light.
Patent
A metamaterial waveguide lens
TL;DR: In this paper, a metamaterial waveguide structure is disclosed, which includes a plurality of complementary metammaterial elements patterned on a conducting surface of the waveguide, and a Rotman lens is compressed by 27 percent along the optical axis while maintaining the beam steering range, gain and side lobe amplitudes over a broad frequency range.
