A touch panel includes a first plurality of echelons arranged on a substrate along a first centerline at a first angle and a second plurality of echelons arranged on a substrate along a second centerline at a second angle. A first wave generator on an end of the substrate is configured to transmit a first wave along the first centerline of the first plurality of echelons and a second wave generator on an end of the substrate is configured to transmit a second wave along the second centerline of the second plurality of echelons. First and second trapping slots are positioned parallel to their respective plurality of echelons. |
