High‐Sensitivity Terahertz Gas Sensing Enabled by Undercut Metal‐Dielectric‐Metal Metamaterial

open access: yesAdvanced Materials Interfaces, EarlyView.
A terahertz (THz) metamaterial gas sensor is demonstrated using a metal–dielectric–metal (MDM) absorber with an undercut dielectric layer, which enlarges the gas‐replaced volume and strengthens refractive‐index perturbation of the resonant mode. A reflection dip at 0.766 THz is observed, and acetone–nitrogen tests yield concentration‐dependent shifts ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

open access: yesAdvanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on
