Terahertz Waveform‐Selective Antenna Using a Patch Structure Loaded with Nonlinear Circuits

Advanced Photonics Research, Volume 7, Issue 2, February 2026.
A waveform‐selective antenna that integrates the functions of waveform selectivity, electromagnetic shielding, and EM wave radiation has been proposed. By integrating different nonlinear circuits and selecting appropriate component values, the antenna can achieve high reflection of either a pulse wave or a continuous wave, while allowing the other ...

Enhanced Responsivity, Accuracy, and Stability of Aerosol Jet Printing via Mechanical Switching Valve Assisted Internal Shuttering

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

Liquid Metal Elastomer Based Coplanar Waveguide Transmission Line for Stretchable and Self‐Healing RF Electronics

Advanced Electronic Materials, Volume 12, Issue 4, 18 February 2026.
This work shows the first proof‐of‐concept for fully self‐healing and stretchable coplanar waveguide (CPW) transmission line using printable electrically conductive liquid metal elastomer. RF performance was evaluated in frequency ranging from 1 to 6 GHz under uniaxial tensile strain up to 100%, after self‐healing, and for 1000 cyclic stretch‐release ...
