A microwave analogue of graphene comprised of cylindrical metallic rods arranged in a honeycomb array is fabricated. Dispersion curves of the bound electromagnetic eigenmodes of the system were experimentally determined by measuring the electric near-fields just above the surface. Two linear crossings are evident in these dispersion curves at each of the K and K0 points of the Brillouin zone, mimicking the well-celebrated Dirac cones in graphene
