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 polarization of an antenna is the polarization of the radiated fields produced by an antenna, evaluated in the far field. Hence, antennas are often classified as Linearly Polarized or a Right Hand Circularly Polarized Antenna. This simple concept is important for antenna to antenna communication.f one antenna is vertically polarized and the other is horizontally polarized, the angle is 90 degrees and no power will be transferred. As a side note, this explains why moving the cell phone on your head to a different angle can sometimes increase reception.
