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.
Beam Width The angular range of the antenna pattern in which at least half of the maximum power is still emitted is described as a âBeam Withâ. Bordering points of this main lobe are therefore the points at which the field strength has fallen in the room around 3 dB regarding the maximum field strength. This angle is then described as beam width or aperture angle or half power (- 3 dB) angle - with notation Î (also Ï). The beamwidth Î is exactly the angle between the 2 red marked directions in the upper pictures.
