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.
The array uses electromagnetic wave interference to enhance the radiative signal in one desired direction at the expense of other directions. It may also be used to null the radiation pattern in one particular direction, especially for a receiving antenna in the face of a particular interfering source.
