We demonstrate that a racemic array of helical-shaped metallic wires may behave as the magnetic analog of the conventional wire medium formed by parallel straight metallic wires. It is shown that under transverse electric (TE) excitations, such metamaterial supports a quasi-TEM dispersionless mode with respect to the transverse wave vector component. Exploiting this property, we show that this metamaterial may enable the channeling of the near-field details of TE polarized waves.
