| Abstract: | The structure and propagation characteristics of three-dimensional colloidal crystal are analyzed utilizing the finite-difference time-domain method and experimental results.The diameter,refractive index and layer number of colloidal sphere have effect on the photonic band gap.Colloidal crystal with different parameter is analyzed numerically using FDTD method.Numerical and experimental results show that the microstructures of colloidal crystal from the vertical deposition have a photonic band gap and the c... |
