Chapter 5: Transfer Matrix Method (TMM) and optical mode solvers

This chapter focuses on optical simulation using the Transfer Matrix Method (TMM) and optical mode solvers in OghmaNano. These methods provide efficient approaches for modelling light propagation, interference, reflection, transmission, and optical field distributions in thin-film and guided photonic structures.

The Transfer Matrix Method (TMM) is used to model coherent light propagation through multilayer thin-film structures, including optical filters, anti-reflection coatings, optical cavities, solar cells, and OLEDs. The optical mode solvers calculate the electromagnetic modes supported by waveguides, resonators, and other photonic structures. The material is organised around theory, mathematical derivations, and practical tutorials, allowing users to move from simulation setup to quantitative analysis of transmission, reflection, optical field distributions, guided modes, and field confinement.
