LauchLumerical FDTD and start from an empty object layout, create a region Toolbar: Simulation->Region Object tree: FDTD->Right mouse 2D simulation Medium is water with index of refraction 1.33 X span 100nm, Y span 200 nm
Create a mesh of particular width and depth Toolbar: Simulation->Mesh Object tree: mesh->Right mouse X span 100nm, Y span 200 nm
Create a gold substrate Double click Quadrilateral X span 150nm, Y span 100 nm
Set boundary conditions Bloch boundary condition in the x-axis
Set the material for the substrate Au (Gold) – Johnson and Christy
Second oops Drexler(process 0): The program terminated due to an error:There is no possible parallel processor layout that can be used because the simulation volume is too small. Please reduce the number of processors or contact Lumerical Technical Support for more information.
