IN this method the frequency of a radio-frequency oscillator is modulated by a sinusoidal audio-frequency voltage, and the resultant radio-frequency voltage is applied to a transmitting quartz ...
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 ...
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 ...
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 ...
A new, miniature laser source developed by applied physicists in the Harvard John A. Paulson School of Engineering and ...
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. In order to control ...
Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...
