However, all power applications of superconductors and most other applications requires good current carrying capacity, usually characterized by a critical current Ic, within substantial magnetic fields, usually characterized by a critical magnetic field Hc. Furthermore, a number of other characteristics must be
Beamforming is a type of RF (radio frequency) management in which an access point uses multiple antennas to send out the same signal.
