Our bodies generate extremely weak magnetic fields as electric currents flow through the heart, brain and other tissues.
Abstract: We report on the development of a quantum radio apparatus based on Rydberg atoms and demonstrate long-range radio-frequency (RF) communications with the Rydberg atom radio at a distance of ...
Abstract: We present the design and testing of a 16-bit frequency to digital converter, based on AT89C51 micro-controller, for use in sensing applications. The system generates digital equivalents of ...
