Subwavelength Periodic Lattices for the Design of MMW Components using Ceramic Stereolithography

In this paper we present a ceramic stereolithography fabrication process that enables construction of monolithic all-dielectric MMW front-end components and sub-systems. This process makes it possible to construct all-ceramic parts with arbitrary complex geometries. By adding a lattice substructure to the components, this process makes it possible to achieve a wide range of controllable dielectric constant within the component itself allowing for efficient fabrication of those hardest-to-construct, variable-dielectric components such as planar and matched spherical lenses, photonic filters, and isolated dielectric waveguides
