1. A power receiver, comprising:
a power conversion structure positioned to receive an incoming power beam and configured to convert at least a portion of the incoming power beam to electricity; and
input optics configured to convert a substantially round power beam having a center to a substantially polygonal power beam, the input optics including:
a first set of reflection surfaces configured to shift a first portion of the substantially round power beam away from the center; and
a second set of reflection surfaces configured to shift a second portion of the substantially round power beam away from the center, the second set of reflection surfaces being positioned at an angle to the first set of reflection surfaces.
