Nanophotonics, Volume 15, Issue 15, 13 August 2026.This work presents a NURBS‐enabled metasurface design framework that combines freeform meta‐atom parameterization with Transformer‐based deep learning. The unified mathematical representation expands geometric degrees of freedom while enabling efficient optical‐response prediction and inverse design.

Tunable active bandpass filter design
Electronics Letters, 2011 A tunable active bandpass filter that uses control voltage to select passband frequency response is presented. The proposed topology basically consists of a cascoded current-injection active inductor so as to tune passband frequency response from 2.35 to 3.66 GHz and extend the available bandwidth.

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.Supercritical CO2 foaming of fully amorphous PLA/PHA blends produced low‐density closed‐cell foams with fine cellular morphology. Blending with PHA enhanced biodegradation under simulated home‐composting conditions, achieving up to 84% mass loss after 4 months, whereas marine degradation remained limited and was mainly restricted to the PHA component ...
