Abstract |
Scales from specific weevils, longhorns and butterflies have been shown to internally contain a photonic structure that can be described as the agglomeration of photonic crystallites. Usually, the same local photonic structure is found in all crystallites, with different orientations. This distribution is investigated by analysing a large amount of fractured scales. The visual effects produced by fractioning the photonic-crystal into the aggregation of reoriented photonic crystallites can be, for increasing disorder, (1) the loss of iridescence and the loss of metallicity for diffuse coloration, (2) the loss of coloration. |
