Broadband Terahertz Metalenses Based on Printed Circuit Board Fabrication (Advanced Optical Materials 11/2024)

Abstract
Broadband Terahertz Metalenses Aggressive discretization in metalens design dramatically relaxes the feature size tolerance, making it possible to construct high-performance THz meta-devices using established printed circuit board (PCB) technology. As examples, Alex M. H. Wong and co-workers demonstrate two PCB-based metalenses working for single and dual polarizations, respectively (see article number 2302459). These metalenses feature a very large numerical aperture of 0.86 and achieve diffraction-limited focusing over a broad bandwidth of 240–400 GHz. PCB fabrication can dramatically lower the fabrication cost and time for THz meta-devices and open doors to many practical applications.
