Surface Plasmon Enhanced Photoluminescence of Carbon Dots Formed In Situ on Silver Gratings
Advanced Science, Volume 13, Issue 27, 13 May 2026.Carbon emitters formed in situ on a silver grating via plasmonic catalysis yield enhanced spontaneous emission by preferential radiative decay into surface plasmons. Enhancement manifests as emission exhibiting characteristics of coherence (polarization, directionality), and accelerated lifetimes of ∼30 ps, yielding Purcell factors of ∼70.

Advanced Electronic Materials, Volume 12, Issue 10, 25 May 2026.A flexible ternary composite combining barium hexaferrite (BHF), Co–Microwires, and silicone rubber exploits magnetic–conductive synergy to deliver tunable X‐band EMI shielding, reaching a 16.9 dB at 9.8 GHz (surpassing the 10 dB industrial benchmark). Shielding behavior shifts between reflection and absorption with BHF loading and Co–Microwires counts

Continuously Tunable Dual-Mode Bandstop Filter [PDF]
IEEE Microwave and Wireless Components Letters, 2018 A varactor-based tunable bandstop filter has been proposed in this article. The proposed filter is based on a dualmode circuit developed by introducing inductive and capacitive couplings into a notch filter. The frequency tunability is achieved by using varactor diodes instead of the lumped capacitors in the circuit.
