Finite Difference Time-Domain Modelling of Metamaterials: GPU Implementation of Cylindrical Cloak
Blog Article
Finite difference time-domain (FDTD) technique can be used to model metamaterials by treating them as dispersive material.Drude or Lorentz model can read more be incorporated into the standard FDTD algorithm for modelling negative permittivity and permeability.FDTD algorithm is readily parallelisable and can take advantage of GPU acceleration to achieve speed-ups of 5x-50x depending on hardware setup.Metamaterial scattering problems are implemented using dispersive simply southern cat shirt FDTD technique on GPU resulting in performance gain of 10x-15x compared to conventional CPU implementation.
