Active terahertz metamaterial devices
TL;DR: An active metamaterial device capable of efficient real-time control and manipulation of terahertz radiation is demonstrated, which enables modulation of THz transmission by 50 per cent, an order of magnitude improvement over existing devices.
Journal ArticleDOI
Broadband Modulation of Light by Using an Electro-Optic Polymer
Mark Lee,Howard E. Katz,Christoph Georg Erben,Douglas M. Gill,Padma Gopalan,Joerg Heber,David J. McGee +6 more
TL;DR: An appropriate choice of polymers is shown to effectively eliminate the factors contributing to an optical modulator's decay in the high-frequency response, and the resulting device modulates light with a bandwidth of 150 to 200 GHz and produces detectable modulation signal at 1.6 THz.
Journal ArticleDOI
Electrically resonant terahertz metamaterials: Theoretical and experimental investigations
Willie J. Padilla,M. T. Aronsson,Clark Highstrete,Mark Lee,Antoinette J. Taylor,Richard D. Averitt +5 more
TL;DR: In this paper, the authors presented a class of artificial materials that exhibit a tailored response to the electrical component of electromagnetic radiation, including regions of negative permittivity ranging from 0.3em to 1.1m.
Journal ArticleDOI
Complementary planar terahertz metamaterials
Hou-Tong Chen,John F. O'Hara,Antoinette J. Taylor,Richard D. Averitt,Clark Highstrete,Mark Lee,Willie J. Padilla +6 more
TL;DR: The frequency dependent effective complex dielectric functions are extracted from the experimental data and, in combination with simulations to determine the surface current density and local electric field, provide considerable insight into the electromagnetic response of the planar metamaterials.
Journal ArticleDOI

TL;DR: This functionally non-equivalent yet cooperative interaction between Wnt and RSPO ligands establishes a molecular precedent for regulation of mammalian stem cells by distinct priming and self-renewal factors, with broad implications for precise control of tissue regeneration.
