Beam steering: Changing the direction of the main lobe of a radiation pattern.

Note: In radio systems, beam steering may be accomplished by switching antenna elements or by changing the relative phases of the rf signals driving the elements. In optical systems, beam steering may be accomplished by changing the refractive index of the medium through which the beam is transmitted or by the use of mirrors or lenses.

Beam-powered propulsionBeam-powered propulsion is a class of spacecraft propulsion mechanisms that use energy beamed to the spacecraft from a remote power plant. Many proposed spacecraft propulsion mechanisms use power in the form of electricity. Usually these schemes assume eiBeam diameterBeam diameter Of an electromagnetic beam, along any specified line that (a) intersects the beam axis and (b) lies in any specified plane normal to the beam axis, the distance between the two diametrically opposite points at which the irradiance is a speciBeam divergenceBeam divergence Of an electromagnetic beam, in any plane that intersects the beam axis, the increase in beam diameter with distance from the aperture from which the beam emerges. Beam divergence is usually used to characterize electromagnetic beams in the

In the radio regime, of an antenna pattern, the angle between the half- power (3- dB) points of the main lobe, when referenced to the peak effective radiated power of the main lobe.BeamA beam of light is a light ray. The beam in nautical terminology refers to the most extreme width (or breadth) of a vessel, or a point alongside the ship at the mid-point of its length. The latter usage also appears in the expression "abeam". A beam is a
