Axions are well motivated particles that could make up most or all of the dark matter if they have masses below 100 mu eV. Microwave cavity techniques comprised of closed resonant structures immersed in solenoid magnets are sensitive to dark matter axions with masses of a few mu eV but face difficulties scaling to higher masses. We present the a novel detector architecture consisting of an open, Fabry-Perot resonator and a series of current-carrying wire planes and demonstrate this technique with a search for dark matter axionlike particles called Orpheus. This search excludes dark matter axionlike particles with masses between 68.2 and 76.5 mu eV and axion-photon couplings greater than 4 x 10(-7) GeV-1. We project that the fundamental sensitivity of this technique could be extended to be sensitive to couplings below 1 x 10(-15) GeV-1, consistent with the DFSZ model of QCD axions.
