The art of light engineering unveils a world of possibilities through the meticulous
manipulation of photonic properties such as intensity, phase, and polarization. Precision
control over these properties finds application in a variety of fields spanning
communications, light–matter interactions, laser direct writing, and imaging. Terahertz (THz)
range, nestled between microwaves and infrared light, stands out for its remarkable ability to
propagate with minimal losses in numerous dielectric materials and compounds, making …

Structured terahertz light in the form of an Airy beam–resembling the “THz sun”–illuminating
Fresnel, Fibonacci and Bessel shaped THz beams illustrates the comprehensive study on
THz light engineering in nonparaxial lensless imaging systems based on silicon diffractive
optics (see article number 2301197 by Sergej Orlov, Rusnė Ivaškevičiūtė-Povilauskienė,
and co-workers). The background depicts the numerically estimated modulation transfer
map dependencies on the distance between imaged object and the optical element.
