N2 - In this paper, we present measurements of a prototype metamaterial flat lens. Flat lenses with short focal lengths are interesting due to their potential use in remote sensing for both space-based cubesat applications and larger form factors. Our metamaterial flat lens was manufactured by using 11 layers of RO3003 circuit board laminate with etched sub-wavelength-sized copper patterning. The copper patterning is designed in such a way as to maximize the transmittance of the lens while applying the correct phase shift across the lens plane to give the lens Gaussian focal properties. The lens was measured by scanning a receiver horn through one axis of the image plane of a transmitting horn. This measurement demonstrated that the waist of the focused Gaussian beam is 30% wider than ideal. It is suspected that this non-ideality is caused by phase error in the design process. We have created an electromagnetic simulation based on Fourier optics which will soon be able to characterize such non-idealities. Further measurements will be useful to fully characterize the lens's focal properties and determine how much loss it incurs.
