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 … Web5 Mar 2024 · The terahertz band of electromagnetic waves demonstrates several attractive characteristics, including non-ionization, fingerprint spectrum, sensitivity to weak resonance, and strong penetration of nonpolar materials, which have promising applications in communication [ 1 ], sensing [ 2 ], and imaging [ 3 ].
