The terahertz range is generally defined as the portion of the electromagnetic spectrum that
lies between 100 GHz and 10 THz. It is situated above the microwave range, and below the …

Over the last 20 years, thin and lightweight optical elements have become very desirable,
especially for the terahertz (THz) range. Reduction of the volume of optical elements …

Terahertz and millimeter waves penetrate various dielectric materials, including plastics,
ceramics, crystals, and concrete, allowing terahertz transmission and reflection images to be …

A 3D printer was used to realize custom-made diffractive THz lenses. After testing several
materials, phase binary lenses with periodic and aperiodic radial profiles were designed …

We demonstrate two algorithms used forreconstructing the target's structure basedon the
diffracted pulses and additionallyshow that a three-dimensional target can bereconstructed …

We report the achievement of the first images to our knowledge obtained with a fractal zone
plates (FraZPs). FraZPs are diffractive lenses characterized by the fractal structure of their …

We demonstrate experimentally and by simulations a method for using thin nanostructured
plasmonic metasurfaces to design diffractive Fresnel zone plate lenses that focus pairs of …

We have designed, fabricated and experimentally characterized a lens for the THz regime
based on artificial dielectrics. These are man-made media that mimic properties of naturally …

Pulsed terahertz (THz) wave sensing and imaging is a coherent measurement technology.
Like radar, based on the phase and amplitude of the THz pulse at each frequency, THz …
