Three‐dimensional single‐shell dielectric lens design using complex coordinates and local axis‐displaced confocal quadrics

Abstract: This study proposes an analytical formulation in complex coordinates to synthesise threedimensional single-shell dielectric lens surfaces. An exact formulation based on geometrical optics is developed, and the synthesis problem is modelled as a non-linear second-order partial differential equation of the Monge-Ampère (MA) type. An alternative numerical scheme based on axis-displaced confocal quadrics is used to locally represent the surface of dielectric lens. The advantage of this approach is to analytically … Show more
