## Abstract

In one embodiment, a touch sensor includes a substrate and a mesh of conductive material formed on the substrate and configured to extend across a display. The mesh includes first lines of conductive material that are substantially parallel to each other. The first lines extend across at least a portion of the display at a first angle relative to a first axis. The first lines are separated from each other along the first axis by a sequence of separation distances having corresponding magnitudes, where magnitudes of more than one separation distance from among the sequence of separation distances are based on a phasor step θ and a phasor magnitude of at least one phasor.
