We describe the design and function of a circular magnetic waveguide for
deBroglie waves produced from wires on a microchip. The guide is a
two-dimensional magnetic minimum for trapping weak-field seeking states of
atoms or molecules with a magnetic dipole moment. The design consists of seven
circular wires sharing a common radius. We describe the design, the
time-dependent currents of the wires and show that it is possible to form a
circular waveguide with adjustable height and gradient while minimizing
perturbation resulting from leads or wire crossings. This maximal area geometry
is suited for rotation sensing with atom interferometry via the Sagnac effect
using either cold atoms, molecules and Bose-condensed systems.
