1. An emitter array, comprising:
a first emitter comprising a first plurality of radial extensions and a first plurality of trenches,
wherein a first trench, of the first plurality of trenches, is arranged between a first pair of radial extensions, of the first plurality of radial extensions, and
wherein the first plurality of radial extensions define a first total of radial extensions; and
a second emitter, adjacent to the first emitter, comprising a second plurality of radial extensions and a second plurality of trenches,
wherein a second trench, of the second plurality of trenches, is arranged between a second pair of radial extensions, of the second plurality of radial extensions, and
wherein the second plurality of radial extensions defines a second total of radial extensions that is different than the first total of radial extensions.
