Resumen:
We present a novel simulation method to investigate the multicolored effect of the Diachea leucopoda (Physarales order, Myxomycetes
class), which is a microorganism that has a characteristic
pointillistic iridescent appearance. It was shown that this appearance
is of structural origin, and is produced within the peridium -protective
layer that encloses the mass of spores-, which is basically a
corrugated sheet of a transparent material. The main characteristics of
the observed color were explained in terms of interference effects using
a simple model of homogeneous planar slab. In this paper we apply a
novel simulation method to investigate the electromagnetic response of
such structure in more detail, i.e., taking into account the
inhomogeneities of the biological material within the peridium and its
curvature. We show that both features, which could not be considered
within the simplified model, affect the observed color. The proposed
method is of great potential for the study of biological structures,
which present a high degree of complexity in the geometrical shapes as
well as in the materials involved.
