Parametric Sweep tool The simulation tools used to simulate 3D nanostructures (or metamaterials/metasurfaces) usually come with a built-in operation of parametric sweep (or simply sweep ). A parametric sweep, as evident by its name, sweeps a particular parameter or a set of parameters to evaluate the results. A parametric sweep

3D simulations using software We covered 2D simulations in our previous discussion on 2D thin film calculations. Here we will introduce the software techniques which are employed to find the reflection, transmission, and phase from 3D objects, and to optimize the resonances produced by the said objects. We will only
