Schematic of THz near-field microscopy based on an air-plasma dynamic aperture. Two femtosecond laser pulses were focused in mutually perpendicular directions to generate two air-plasmas (Plasma1 and ...

Modern microwave technology, including the generation, manipulation, and detection of microwaves, plays a vital role in various fields, such as high-frequency integrated circuits, quantum computing, ...

In NPL's Quantum Materials and Sensors group, we study the nanoscale properties of emerging quantum materials, including graphene, photonic metamaterials, and topological insulators. Recently the ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

Three-dimensional (3D) super-resolution microscopy is essential to study the minute structural details of cells and analyze molecular dynamics. Recently, researchers at Ludwig-Maximilians-Universität ...

As a novel far-infrared inspection method, the development of terahertz (THz) imaging technology has attracted considerable attention in recent years. With unique properties of THz radiation, such as ...
