Abstract
We describe a new methodology for creating flat lenses operating in the microwave spectrum using a custom designed additive manufacturing system. This method utilizes a novel dry powder 3D printing system to achieve graded index lenses integrated within a structural composite. We also describe a new iterative dot patterning algorithm to achieve a desired graded dielectric distribution, and we compare the iterative dot patterning algorithm to other dot patterning techniques. Computational and experimental results are provided validating the design and fabrication process.
