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 ...

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.
