Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers ...

Hierarchical magnetic graphene–SiCN aerogels were constructed via a stepwise confinement strategy, in which ZIF-derived magnetic nanoparticles and a polysilazane-derived SiCN ceramic layer were ...

Scientists from University of Regensburg, Massachusetts Institute of Technology, Moscow institute of Physics and Technology, and University of Kansas have discovered abnormally strong light absorption ...

Skoltech researchers have developed an ultrathin carbon nanotube coating that absorbs terahertz radiation on silicon waveguides, offering a practical fix for one of the biggest obstacles facing future ...

Researchers have discovered that proteins, specifically bovine serum albumin (BSA), can improve the microwave absorption capabilities of metal-organic frameworks (MOFs). The optimized composite, 2-BSA ...

With the development of aerospace technology, the demand for stealth in high-temperature components of aircraft such as engines has become increasingly urgent. Furthermore, the trend of radar ...

In order to control noise, designers must first determine where the noise source or sources are how much each is contributing to the overall level, and their frequency signatures. This can be done ...
