Ampere’s Law relates the total magnetomotive force along a closed loop and the net current enclosed by the loop.
Antenna is a method that is used for converting the guided waves present in a waveguide, feeder cable, or transmission line into radiating waves traveling in free space, or vice versa.
Attenuator is a passive device that is used to reduce the strength or amplitude of a signal.
Attenuation constant (α) represents attenuation of the wave on the transmission line. For a positive α, the amplitude exponentially decreases as a function of distance. The unit of attenuation constant is nepers/m.
Azimuth (or bearing) resolution is the ability of a radar system to separate objects at the same range but at slightly different ...
