Abstract
We recently showed (Savini 2012) the use of stacked graded photolithographic capacitive metal-mesh structures on polypropylene substrates to produce a thin flat Wood lens working in a wide (90%) bandwidth. Here an additional impedance-matched layer is designed to improve the original lens efficiency in a wide band around the central frequency of operation.
