Terahertz Dipole Nanoantenna Arrays: Resonance Characteristics
Resonant dipole nanoantennas promise to considerably improve the capabilities of terahertz spectroscopy, offering the possibility of increasing its sensitivity through local field enhancement, while in principle allowing unprecedented spatial resolutions, well below the diffraction limit. Here, we investigate the resonance properties of ordered arrays of terahertz dipole nanoantennas, both expe...
متن کاملDomino plasmons for subwavelength terahertz circuitry.
A new approach for the spatial and temporal modulation of electromagnetic fields at terahertz frequencies is presented. The waveguiding elements are based on plasmonic and metamaterial notions and consist of an easy-to-manufacture periodic chain of metallic box-shaped elements protruding out of a metallic surface. It is shown that the dispersion relation of the corresponding electromagnetic mod...
متن کاملMeander Line Antennas
SkyCross' state-of-the-art antennas are smaller and can be embedded directly within the handset. In addition, they feature better gain and improved efficiency, resulting in longer battery life than other handsets currently available on the market today. Furthermore, MLA technology allows engineers to design ultra broadband antennas capable of operating at multiple frequencies and in a variety o...
متن کاملNanoantenna coupled UV subwavelength photodetectors based on GaN.
The integration of nano structures with opto-electronic devices has many potential applications. It allows the coupling of more light into or out of the device while decreasing the size of the device itself. Such devices are reported in the VIS and NIR regions. However, making plasmonic structures for the UV region is still a challenge. Here, we report on a UV nano-antenna integrated metal semi...
متن کاملA dual band terahertz metamaterial absorber
We present the design, fabrication and characterization of a dual band metamaterial absorber which experimentally shows two distinct absorption peaks of 0.85 at 1.4 THz and 0.94 at 3.0 THz. The dual band absorber consists of a dual band electric-field-coupled (ELC) resonator and a metallic ground plane, separated by an 8μm dielectric spacer. Fine tuning of the two absorption resonances is achie...
