Large-Scale, Compound Metaoptics for Complete Wavefront Control
Abstract
In the first year of study, Grbic will theoretically study the proposed method of tailoring both the amplitude and phase of an aperture using paired, reflectionless metasurfaces. Phase retrieval methods will be investigated to determine the phase profiles needed on the phase planes of the metaoptic. Fundamental limits on the minimum separation needed between the two reflectionless metasurfaces (phase planes) to establish targeted aperture fields will also be explored. These fundamental limits will be compared to practical ones imposed by realizable bianisotropic metasurfaces. In the second year, Grbic will pursue the development of paired, reflectionless metasurfaces at near-infrared wavelengths that can generate simple aperture fields with amplitude and phase distributions that vary in two dimensions. In the final year, a compound metaoptic will be experimentally demonstrated that recreates the complex-valued field scattered from an actual three-dimensional object at visible wavelengths.
