Multi-resonant tunable absorber of terahertz metamaterial based on GaAs and VO2
Based on the fact that the conductivity of photosensitive semiconductors can be regulated by external pump light, a metamaterial absorber with single-band and dual-band switchable in terahertz region is designed by replacing gallium arsenide (GaAs ...

Terahertz Nanofocusing with Cantilevered Terahertz-Resonant Antenna Tips [PDF]
We developed THz-resonant scanning probe tips, yielding strongly enhanced and nanoscale confined THz near fields at their tip apex. The tips with length in the order of the THz wavelength (λ = 96.5 μm) were fabricated by focused ion beam (FIB) machining and attached to standard atomic force microscopy (AFM) cantilevers.

An ultra-broadband terahertz absorber at high terahertz frequency
Abstract Broadband absorber at high terahertz frequency is highly required for applications in imaging, detecting, electromagnetic stealth. Although intensive investigations of the broadband absorber have been taken, the challenges still exist both in design and fabrication of an ultra-broadband absorber at high frequency.
