The arrow in the middle of the figure shows a different circle where the mesh does not go through the center of the circle. For example, the left arrow shows a mesh line going through the center of that circle. For example, the following figure shows a PC array, where the FDTD mesh isĪn integer multiple of the PC unit cell. This requires careful setup of some parameters such as sources and mesh to avoid breaking the periodicity of the system. Multiple unit cells in the FDTD simulation regionĭue to the rectangular nature of the FDTD solver region, it may be necessary to include multiple PC unit cells in the solver region. Below is the obtained results for mentioned structures:ĭescription of important objects and settings used in this model A more detailed description of the process is presented in the rectangular lattice bandstructure example. The script will calculate and plot the bandstructure. Open the FDTD file and run the associated script file.
