It is possible to fully absorb electromagnetic radiation using an anisotropic crystal, report scientists. Electromagnetic energy harvesting in the visible spectrum is very important for photovoltaics ...
A team of authors from MIPT, Kansas State University, and the U.S. Naval Research Laboratory have demonstrated that it is possible to fully absorb electromagnetic radiation using an anisotropic ...
Porous carbon materials with good microwave absorption properties were prepared by Friedel-Crafts reaction and high-temperature carbonization using inexpensive coal tar pitch as carbon source. Porous ...
