Dispersion Characteristics of Additive-Manufactured Metasurfaces

This paper presents an efficient and accurate approach for the analysis of additive-manufactured metasurfaces (MTSs) consisting of dielectric posts grown on a grounded slab. The formulation is based conventional effective medium theory that allows modeling such MTSs as uniaxially anisotropic grounded slabs. This procedure can be used to effectively characterize the surface waves supported by additive-manufactured MTSs, as needed in the design of planar lenses and leaky-wave antennas.
