A terahertz (THz) metamaterial biosensor based on four identical resonators is experimentally demonstrated, and high sensitivity achieved by exciting synchronous inductor-capacitor oscillations in a unit cell. The effect of geometries the resonance frequency sensor investigated using finite integration time domain method, simulated 85 GHz per refractive index unit. sample fabricated surface micromachining process characterized THz spectroscopy system combined with bovine serum albumin (BSA)...
We demonstrate an electrically triggered tunable terahertz (THz) band-pass filter based on vanadium dioxide (VO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) embedded hybrid metamaterials. The unit cell of the consists two cross resonators and a central bar. phase transition VO is induced by ohmic heating transmission can be modulated applied currents. mechanism tunability that conductivity film changes with relation between upper...

We present the experimental and numerical results of two-dimensional x-ray imaging due to fast electron transport in a solid target. A 40-μm-thick copper film target is irradiated by 100 mJ, 50 fs normal incident laser pulse. The full width at half maximum photon dose 25 μm, divergence angle electrons 25°–30°, which detected pin-hole technique. surface plasma layer compressed ponderomotive force into depth 0.2λ. wave accompanied transporting studied dividing layers radial direction. narrow...
A symmetry broken hexagram metamaterial (SBHM) is presented to enhance the polarization sensitivity, and thus realize mechanically controlling transmissions of tri-band in terahertz (THz) region. This SBHM has different electromagnetic response for rotating clockwise anticlockwise, respectively. When incident THz wave polarized direction [Formula: see text], three stopbands with central frequencies at 0.36 THz, 0.52 0.75 rotates transmission increases from 0.17 0.85, its modulation depth...
