Phase I results will provide definitive proof that an integrating sphere for RF applications is feasible.This will be demonstrated through the planar design and print of the metamaterial un-collimator. 3D printing opens the door to complex features and high resolution printers can achieve the necessary intricate details required to make this work.Additive manufacturing (AM) has continued to mature and can more easily print any shape with exceptional precision which is a critical feature for microwave range applications.In addition to any shape, AM also has access to a very wide range of materials and including materials that have good EM properties. Typical spheres that are effective in operation are 100s of times the radius of the wavelength.Shrinking these down simply would impose non-functioning devices due to the fundamental nature of how integrating spheres work.To overcome this, novel metamaterial designs have shown it is possible to collimate, bend, move, direct and scatter EM waves in a single material with a deliberate but complex designMicrowave Theory and Techniques (an IEEE phrase),Quasi Optical Techniques,Radio frequency measurements,Radio Frequency Emissions
