1. A structure, comprising:
a transmissive filled volume with a three-dimensional volumetric distribution of dipole structures distributed throughout the volume with interelement spacings in all three dimensions less than one-half of the smallest wavelength of an operational bandwidth,
wherein a dipole value of each dipole structure is selected for the volumetric distribution to approximate a continuous refractive index distribution within the volume to convert a plurality of input reference waves passing through the volume to a target plurality of output object waves.
