Evolving random fractal Cantor superlattices for the infrared using a genetic algorithm
2016
Journal of the Royal Society Interface
Preserved Fulltext
A genetic algorithm is used to evolve optimal fractal random Cantor bars with multiple generators targeting several desired optical functions in the mid-infrared and the near-infrared. ...
Fractal geometry, often described as the geometry of Nature, can be used to mimic structures found in Nature, but deterministic fractals produce structures that are too 'perfect' to appear natural. ...
