1. A spatially-fed high-power amplifier comprising:

  • one or more curved reflectors having an associated one or more radio-frequency (RF) reflective surfaces having curvatures configured to reflect an initial wavefront and generate a reflected wavefront; and

    a spatially-fed active array amplifier configured to amplify the reflected wavefront to generate a high-power planar wavefront, the curvatures of the one or more reflective surfaces to at least in part compensate for an amplitude taper of the initial wavefront and provide the reflected wavefront with substantially uniform amplitude when incident on the spatially-fed active array amplifier,wherein an RF source generates the initial wavefront having the amplitude taper.
