Lenster - A mm-wave flat lens: Further analysis

A flat lens-filter (or lenster) has recently been produced using capacitive metal-mesh structures on polypropylene substrate. The prototype was designed using a combination of a transmission line method(TLM) and HFSS. Its performance was measured and compared to a standard polypropylene lens. We propose to perform further measurements, focusing on the phase, to give a deeper understanding on how the lens performs. This will allow to verify the tlm model used to design the lens, which will aid in designing future prototypes.
