General 4×4 transfer-matrix method (TMM) for optical simulations of isotropic and anisotropic multilayer structures. C++ core with Python bindings.

Simulation and design of a single-mode SOI rib waveguide with zero birefringence using EIMS mode solver.

Domain-agnostic recursive simulation engine implementing coherence-preserving, observer-constrained feedback across physical and symbolic substrates, originating in birefringent optics under a Codex-symmetric / asymmetric architecture.

An effective field theory on a Riemann–Cartan manifold in which torsion is encoded by a scalar field, providing a geometric framework for gravity and cosmology beyond standard curvature-only models.
