Abstract
A gradient-index (GRIN) lens comprises an input surface defined by a body configured to receive electromagnetic (EM) waves from an aperture-constrained array; and an output surface defined by the body configured to output phase-aligned EM waves based on the received EM waves from the aperture-constrained array. The GRIN lens can be dimension-constrained in at least one dimension and can have a non-linear permittivity taper in at least a first dimension. The GRIN lens can provide gain for the received EM waves from the aperture-constrained array.
