Analytically Co‐Designed Absorption‐Diffusion Coding Metasurface for RCS Reduction

Microwave and Optical Technology Letters, Volume 68, Issue 10, October 2026.
ABSTRACT This work proposes a novel and simple design method for an absorption‐diffusion metasurface, combining a coding diffusion‐type metasurface with an absorbing layer. The diffusion and absorption properties are obtained through an analytical co‐design methodology derived from a straightforward Smith chart‐based construction.

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...
