1. A touch panel comprising:
- a first plurality of echelons arranged on a substrate along a first centerline, each echelon in the first plurality of echelons being arranged at a first angle in relation to the first centerline;
a first wave generator on an end of the substrate configured to transmit a first wave along the first centerline of the first plurality of echelons;
a second plurality of echelons arranged on a substrate along a second centerline, each echelon in the second plurality of echelons being arranged at a second angle in relation to the second centerline;
a second wave generator on an end of the substrate configured to transmit a second wave along the second centerline of the second plurality of echelons;
a first trapping slot positioned parallel to the first plurality of echelons; and
a second trapping slot positioned parallel to the second plurality of echelons.

Abstract
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.
