Trapped ions are a promising system for building quantum simulators. For a given simulation problem, it is advantageous if we can individually trap the ions in a well-defined spatial arrangement with specified trap curvatures. We introduce an efficient method for constructing arbitrary two-dimensional (single- and multi-layered) arrays of electric microtraps by calculating and optimizing the shapes of the necessary electrodes. Our method allows for large-scale periodic microtrap designs with maximal trapping depths for a given simulation unit cell. In addition to the general method, we present several examples, including a quantum simulator for the Kitaev toric code [1].
