Photonic bands diagram was founded by finite difference time domain method (FDTD) method for 3D model of 2D photonic crystal structure. The FDTD method was chosen to investigated an impact of side-walls angle on the photonic bands formation.
Dedicated Matlab script was written to process FDTD data including a method for unfolding optical bands for triangular symmetry pattern.
- optical resonance behaviour of a photonic crystal based structures FDTD simulation,
- removal of folded optical bands from obtained data by an additional Matlab script.
- Bash scripting.
