N2 - It has been shown that Transformation Optics (TO)-derived gradient-index (GRIN) lenses often outperform more traditional GRIN designs. In order to better understand the origins of this performance improvement, such TO-derived solutions have previously been decomposed into a 2D-polynomial basis, which unveiled the presence of large radial-axial 'cross-term' contributions to the index profile. While these terms are crucial in maximizing the performance of GRIN lenses, finding the optimal index profile becomes a more challenging problem due to the expanded number of input variables. However, this optimization process can be considerably accelerated through the introduction of surrogate models at several stages of the design process.
