Photonic Generation of Ultrawideband (UWB) Pulse With Tunable Notch-Band Behavior

IEEE Photonics Journal, 2012
A photonic approach to generating the ultrawideband (UWB) pulses with tunable band-rejection behavior based on a negative coefficient two-tap microwave photonic filter is proposed and experimentally demonstrated. To avoid the interference between UWB and

Phase-modulated radio over fiber multimode links

Optics Express, 2012
We present the first experimental demonstration of a phase-modulated MMF link implementing high-frequency digital transmission in a cost-effective solution based on direct detection. Successful subcarrier transmission of QPSK, 16-QAM and 64-QAM data channels for bit rates up to 120 Mb/s through a 5 km MMF link is achieved over the microwave region ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, Volume 28, Issue 11, 3 June 2026.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
