layerabsorption

Layerabsorption is a phenomenon observed in the field of optics and photonics, where light is absorbed by a material in a manner that depends on the number of layers through which it passes. This effect is particularly relevant in the design and analysis of multilayer optical coatings, which are used to enhance or suppress the reflection and transmission of light.

In a multilayer structure, each layer contributes to the overall absorption of light. The absorption coefficient

The absorption in each layer can be calculated by considering the product of the absorption coefficient and

Layerabsorption is also relevant in the study of photonic crystals and metamaterials, where the periodic or
