We describe basic periodic trapping configurations for
ultracold atoms above surfaces. The approach is based on a simple
wire grid and can be scaled to provide large arrays of
periodically arranged magnetic or magneto-optical traps. The unit
cells of the trap lattices are based on crossed wire segments. By
alternating the current directions in the wires of the grid it can
be distinguished between 3 basic lattice configurations. As a
first demonstration, we used macroscopic wires in a 2 layer
configuration to realize the unit cells of the lattices. With this
experimental setup, we observe two of the basic unit cells and an
array of magneto optical traps.
