Architected lattice materials are some of the stiffest and strongest materials at ultra‐light density (<10 mg cm−3), but scalable manufacturing with high‐performance constituent materials remains a challenge that limits their widespread adoption in load‐bearing applications. We show mesoscale, ultra‐light (5.8 mg cm−3) fiber‐reinforced polymer composite lattice structures that are reversibly assembled...
Global pressure to use spectrum more efficiently has sparked a great deal of research to mitigate spectral and spatial congestion between radar and radio systems operating in a shared spectrum access environment. This paper summarizes an algorithmic method of interference cancellation that enables the radar and radio to operate with reduced spatial and spectral separation. These performance improvements...
This paper introduces RadioBOT, a flexible system of mobile robots for acquisition of radio frequency data. The motivation for such a test system is described, namely the difficulty in acquiring real world data for the purpose of spatial cognitive radio (CR) research. Some current areas of CR research are presented for which RadioBOT can gather data. We then describe the hardware and software components...
