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.
Directional TV antennas are antennas designed to pick up signals in the direction you point them. Omni-directional antennas are designed to pick up channels in all directions. This tradeoff off is done by focusing the antenna gain, which is different from amplifier gain.
