Chapter 5: Wave optics, FDTD, mode solvers & TMM

This chapter collects OghmaNano’s wave-optics modelling tutorials for analysing electromagnetic light propagation across multiple physical regimes. It includes transfer-matrix methods (TMM) for thin-film stacks, eigenmode solvers for waveguides and resonators, and full-field finite-difference time-domain (FDTD) simulations for time-resolved device analysis.

Together, these pages cover thin-film interference filters, guided modes, resonant photonic structures, and detector-based performance metrics such as transmission, reflection, modal confinement, and time-domain energy flow. The material is organised as practical, runnable tutorials progressing from editor setup through to quantitative device analysis.
