WebMay 23, 2024 · The finite square well is a unitary problem that does not feature absorption at all. The trade-off is between transmission and reflection. The OP's concern that when light is resonant with an atomic transition, we would usually expect absorption, is therefore largely a different problem. The finite potential well (also known as the finite square well) is a concept from quantum mechanics. It is an extension of the infinite potential well, in which a particle is confined to a "box", but one which has finite potential "walls".
