We present designs for multipole ion traps based on a set of planar, annular, concentric electrodes which require only rf potentials to confine ions. These traps have many desirable properties. Depending on one's choice of experimental parameters, we predict that mm-scale surface traps may have trap depths as high as tens of electron volts, or micromotion amplitudes in a 2-D ion crystal as low as tens of nanometers. Several example traps are studied, and the scaling of those properties with voltage, frequency, and trap scale, for small numbers of ions, is derived. Applications to quantum information science, frequency metrology, and cold ion-atom collisions are discussed.
