Design of graded index flat lenses with integrated antireflective properties

We describe a new methodology for designing graded index lenses at microwave wavelengths with integrated antireflective properties. The method leads to a flat lens with minimal reflection losses at a frequency of interest. Both numerical and experimental results for two different design goals are shown to demonstrate the capabilities of the methodology. (c) 2012 Wiley Periodicals, Inc.
