Our research responds, to the need of screening potential security threats concealed by airline passengers, or in parcels for embassies, the topic nowadays essential. The project aims at beam focusing of terahertz radiation. According to classical electromagnetics for Gaussian beams, the focus spot diameter cannot be smaller than c.a the beam wavelength (due to the diffraction limit). The effect is notably for long terahertz wavelengths and hinders its imaging resolution. The recent experiments in the so-called structured light show that the limit is less constrained. The project coalesces two very vibrant fields in photonics: so-called structured light and terahertz techniques. It is predominantly experimental research, pioneering in THz vortices generation and their characterization. The outcome of the project will improve detail resolution in terahertz security scanners and material diagnostics, i.e., terahertz near-field microscopy for semiconductor and material science.
