Abstract

The B-spline modal method is adapted for the design and analysis of nanostructured devices in conical mounting. The eigenmodes in each layer are calculated for two specific polarization states, and then combined for the calculation of the scattering matrices. We take advantage of the sparsity of the generated matrices to decrease the computation time, and adress the need for fast computation in complex systems. Moreover, we demonstrate the physical interest of computing the conical response on various classical structures.
