Abstract
We present computational design and analysis of near-zero-index (NZI) shell structures with elliptical cavities, which can provide directional radiation characteristics when excited by isotropic sources. Alternative strategies, such as geometric shaping of internal cavities, using pyramidal textures, and selecting suitable material properties, are employed to create symmetric and asymmetric beams.
