Flexible terahertz metamaterials: towards a terahertz metamaterial invisible cloak

2008 IEEE International Electron Devices Meeting, 2008
In this work, we present flexible metamaterials on free standing polyimide substrates operating at terahertz (THz) frequencies range. The successful demonstration of THz flexible metamaterials provides a path forward for creating multi-layer non-planar metamaterials such as THz invisible cloak.

Eutectic terahertz metamaterials

2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2013
We present unique phenomena of enhanced transmission of terahertz (THz) waves through a self-organized eutectic metamaterial1. Our experimental results in combination with theoretical calculations show that the experimentally observed enhanced transmission is associated with sub-wavelength waveguiding within the dielectric rods lattice embedded in an ...

Metamaterials for the terahertz gap

2008 33rd International Conference on Infrared, Millimeter and Terahertz Waves, 2008
Metamaterials are engineered materials which offer superb electromagnetic performance over naturally occurring materials, and offer great potential to construct novel devices operating in the terahertz frequency regime. Here we experimentally demonstrate metamaterial narrow band filters, perfect absorbing elements for THz imaging, and ultra-fast THz ...

Self-Powered Terahertz Modulators Based on Metamaterials, Liquid Crystals, and Triboelectric Nanogenerators.

ACS Applied Materials and Interfaces
6G communication mainly occurs in the THz band (0.1-10 THz), which can achieve excellent performance. Self-powered THz modulators are essential for achieving better conduction, modulation, and manipulation of THz waves.

Metamaterial based terahertz detector

2011 International Conference on Infrared, Millimeter, and Terahertz Waves, 2011
We present a metamaterial based terahertz (THz) detector. The detector design, which combines metamaterials and MEMs, is frequency selective, and we have fabricated and tested detectors at 95 GHz and 693 GHz with noise equivalent powers of 1.13 × 10−8 W/√Hz and 2.96 × 10−8 W/√Hz and responsivities of 16,500 V/W and 6,800 V/W, respectively. These values

Superconductor Terahertz Metamaterials

International Conference on Ultrafast Phenomena, 2010
We demonstrate THz metamaterials comprised of high temperature superconducting film (YBa2Cu3O7) replacing the metal structure. They exhibit unique properties that are not achievable using metals, which may result in both interesting applications and underlying physics.
