Abstract :
Transformation Optics (TO) has enabled new methodologies for the design and specification of gradient-index (GRIN) lenses for radio-frequency and optical applications by linking refractive index gradients to a mathematically equivalent change in geometry in an alternative (virtual) space. In this work, concepts from classical optical lens design are interpreted through TO. This is demonstrated by employing the quasi-conformal transformation optics (qTO) approach combined with a powerful global optimization algorithm and a custom ray-tracer well suited for the characterization of optical lenses with arbitrary 2D and 3D gradient index (GRIN) profiles.
