Computing the Scattering of Light from a Rough Surface with a Metal Coating
Application ID: 49891
These examples demonstrate how to compute the total reflection, transmission, and absorption of light when a plane wave, at optical wavelengths, is incident upon a dielectric slab with a thin metal coating. Three examples are included that show:
- An optically flat slab
- A slab with a sinusoidal variation in height
- A slab with random roughness
These model files relate to the blog post: "How to Model Optical Properties of Rough Surfaces".
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
