WebA uniform illumination over a screen is crucial for terahertz imaging. As such, conversion from a Gaussian beam to a flattop beam becomes necessary. Most of the current beam conversion techniques rely on bulky multi-lens systems for collimated input and operate in the far-field. We present a single metasurface lens to efficiently convert a quasi-Gaussian … WebJan 4, 2024 · Our results demonstrate direct pulse shaping in terahertz spectrum, where the amplitude and phase of the input wavelengths are independently controlled through a … ffxi windower mip mapping

Terahertz (THz) wave occupies a broad range of the electromagnetic spectrum between the microwave and infrared (typically 0.1−10 THz), thus bridges electronics and photonics. THz wave exhibits many unique properties. Its low photon energy facilitates non-destructive detection and human … See more The antireflection-layer-integrated metasurface is made by intrinsic silicon, which possesses low absorption and large refractive index in THz range. As shown in Figure 1A, both sides … See more Via rationally designing the spatial orientation of meta-units, the wavefront of THz beam could be freely manipulated. First, an antireflection-layer-integrated metalens is … See more In summary, we propose an integrated antireflection strategy for transmissive THz metadevices. Different THz PB phase metadevices including metalens, metalens array, polarization … See more The bi-layer design, which consists of micro-pillar arrays on both sides of the wafer, is conducted in a same micro-fabrication process on the same silicon wafer. It provides a … See more WebWe propose a topological beam-shaping strategy of terahertz (THz) beams using geometric phase elements made of space-variant birefringent slabs. Quasi … WebAug 2, 2024 · The formation of broadband terahertz vortex and vector beams attracts increasing attention due to the prospects for using such beams in telecommunications, imaging, and sensing of material properties. One of the most effective ways for THz beam shaping is geometric phase approach based on a spin-orbit conversion principle. dentistry brandon
