Abstract

Straight forward design of a three-dimensional microwave lens operating from the X- to K-band is proposed. Two-dimensional Omega-net structures that proved to have a near-zero refractive index with low loss are used as a startup design, and later are optimized and implemented to construct a three-dimensional near-zero refractive index structure. A 3D single-shell Omega-net lens can generate dual near-zero refractive index bands, 9.16GHz-10.32GHz or 5.32% BW and 11.36GHz- 12.62GHz or 5.25% BW. Other two candidates, i.e., a 3D double-shell Omega-net and a 3D diamond double-shell Omega-net lenses are also introduced.
