Abstract

We model a plant leaf by using two-dimensional domain walls with internal structures. Such domain walls can be found as soliton solutions in field theory describing magnetic materials. The radiation scattered by such domain walls behaves quite similar to the spectral reflectance of plant leaves. The model nicely simulates the spectral reflectance of a plant leaf as a function of the wavelength.
