The invisibility cloak has appeared in several films and television shows; it is a fictitious device that can conceal the item inside it. The invisibility cloak has been a hot topic for research in many fields, especially in the military with stealth fighters. Transformation optics allows people to design new materials by controlling the way light propagates using the coordinate transformation method, achieving invisibility. This method's invisibility cloak, however, does a poor job of accurately describing the multilayered cloak's performance in real-world circumstances. In this project, the performance of a multi-layered invisibility cloak will be modelled using MATLAB, and global optimisation tools will be used to optimise the model in order to reduce the intrinsic scatterings caused by discretization and simplification. In most cases, the optimised model not only performs better but also only calls for a small number of layers, making it simple to implement in real manufacturing settings.
