WebA thick lens cannot be characterized by a single focal length measured from a single plane. A single focal length F may be retained if it is measured from two planes, H 1, H 2, at distances P 1, P 2 from the vertices of the lens, V 1, V 2. The two back focal lengths, BFL 1 and BFL 2, are measured from the vertices. The thin lens equations may ... WebDec 17, 2024 · Thus, the photonic crystal waveguides can be integrated directly with the Luneburg lens and fabricated together from the same silicon wafer. In this way, we develop a planar Luneburg-lens antenna with a diameter of 17 mm and seven evenly spaced ports that cover a 120° field of view.
