3D-Printing for Transformation Optics in Electromagnetic High-Frequency Lens Applications
José-Manuel Poyanco, Francisco Pizarro, Eva Rajo‐Iglesias
Abstract
This article presents the design, construction and analysis of a 3D-printed transformed hyperbolic flat lens working on the 30 GHz band. The transformed lens was printed using only one ABS dielectric filament of relative permittivity of 12, varying the infill percentage of each transformed lens section in order to achieve the permittivity values obtained with the transformation optics. The 3D-printed hyperbolic transformed lens exhibits good radiation performance compared to the original canonical lens.
