Simulating Electronic Properties in Microwave Regime

Hello Colleagues,
I am looking for some guidance on defining Fresnel Equations to account for multiple boundary layers. The COMSOL example takes "n_air" and "n_slab," but how does one account for more interfaces and layers (i.e., glass, copper), when defining reflection and transmission coefficients respectively? Do all of the layers have to be defined individually, or are there trigonometric relations that will account for all instances of reflectivity concertedly.
I appreciate any help and/or guidance in advance.

There is a formalism for multiple layers. As one would expect, the complexity of the expressions grows as you add more layers. Here is a link to a paper addressing it: https://www.researchgate.net/publication/236659432_Multiple_reflection_method_for_electromagnetic_waves_in_layered_dielectric_structures (Note that you may have to join researchgate.net to access it, but you can do so for free.)
