Schaefer–Bergmann diffraction

Schaefer–Bergmann diffraction refers to a specific phenomenon related to the diffraction of light or waves when they encounter a periodic structure. This term is often associated with studies in the field of optics or materials science, particularly in the context of understanding how waves interact with different types of materials or surface structures. In general, diffraction occurs when waves, such as light, encounter an obstacle or a slit that is comparable in size to their wavelength.
