Scientists at Harvard create world’s smallest radio out of diamond imperfections
Harvard scientists have created the world’s smallest radio receiver out of diamond imperfections called nitrogen-vacancy (NV) centres. The NV centers are capable of emitting single photons or detect very weak magnetic fields. When the NV centers receive radio waves it will ..
Specific Absorption Rate (SAR)
Specific absorption rate is the measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) in electromagnetic field. The term is not restricted to the absorption of Electromagnetic Feild (EMF) and can be used in terms of ..
