Coherence in the single and multiple scattering of light from randomly rough surfaces
Light scattering from rough surfaces shows enhanced backscattering due to constructive interference. This study explores four types of light scattering enhancements, including transmission, specular, and refraction, in randomly rough surfaces.
Area of Science:
- Optics
- Condensed Matter Physics
- Wave Scattering
Background:
- Enhanced backscattering is a key phenomenon in light scattering from randomly rough surfaces.
- It arises from the coherent interference of multiply reflected optical paths with their time-reversed partners.
- This phenomenon is a manifestation of weak localization in multiple-scattering processes.
Purpose of the Study:
- To theoretically analyze and experimentally investigate various light scattering enhancement phenomena.
- To explore enhancements beyond backscattering, including transmission, specular, and refraction.
- To demonstrate these effects in both one-dimensional and two-dimensional randomly rough surfaces.
Main Methods:
- Theoretical analysis of light scattering from randomly rough surfaces.
- Experimental verification of predicted scattering phenomena.
- Investigation of coherent effects remaining after ensemble averaging.
Main Results:
- Demonstrated enhanced backscattering, a well-defined peak in the retroreflection direction.
- Observed enhanced transmission and enhanced specular reflection due to constructive interference.
- Reported enhanced refraction phenomena.
- Confirmed these enhancements for both 1D and 2D surfaces.
Conclusions:
- Coherent effects significantly influence light scattering from randomly rough surfaces.
- Multiple types of scattering enhancements (backscattering, transmission, specular, refraction) exist.
- These phenomena are crucial for understanding light-matter interactions with disordered surfaces.

Surface Tension and Surface Energy
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
