Enhanced control of transmission/reflection amplitudes using a closed-form slowly varying phase-gradient metasurface GSTC framework

Abstract Although the generalized Snell’s law qualitatively predicts the effect of the phase gradient on wave impedance and parasitic diffractions, a closed-form quantitative relationship among transmission/reflection coefficients, phase gradient, incidence angle, and polarizabil...

Multilayer WS 2 /Borophene/Au/MXene/Cu Metasurface Terahertz Biosensor With Machine Learning‐Augmented Prediction for Label‐Free Brain Tumor Detection

High‐performance terahertz metasurface biosensor is numerically developed for label‐free brain tumor detection. The sensor employs six multilayer elliptical resonators integrating WS 2 , borophene, Au, MXene, and Cu on a graphene‐coated SiO 2 substrate. Three material configurati...
