Adaptive multilevel non-uniform grid algorithm for fast field evaluation in multilayered media

In this work, we introduce a multilevel layered medium NG (ML-LMNG) algorithm that is a multilevel generalization of the two-level LMNG and multi-level free-space NG algorithms. The LMNG algorithm inherits most of the advantages of the free-space NG scheme and offers additional advantages as compared to other fast schemes for layered media when quasi-planar configurations are of interest.
