Freeform optics provides precise control of light for beam shaping and mode conversion, but designing volumetric micro-optical elements requires efficient, low-runtime simulation methods. The wave propagation method (WPM) offers a fast alternative to full-wave solvers for high-index-contrast and non-paraxial systems but lacks differentiability, preventing its use with gradient descent methods for inverse design.
