1. A method performed at least in part by a power system controller that is at least partially hardware, the method comprising:
powering a first voltage source in a first edge opening of a circular disk to cause radiation;
powering a second voltage source in a second edge opening of the circular disk to cause radiation;
powering a third voltage source in a third edge opening of the circular disk to cause radiation; and
powering a fourth voltage source in a fourth edge opening of the circular disk to cause radiation,
where the first edge opening and the second edge opening are along a first common axis,
where the third edge opening and the fourth edge opening are along a second common axis and
where the second edge opening and the third edge opening are about perpendicular to one another
where at an about 0 degree state, the first voltage source is powered with a magnitude of about √2 and a phase of about 45°, the second voltage source is powered with a magnitude of about 1 and a phase of about 0°, the third voltage source is shorted, and the fourth voltage source is shorted,
where at an about 90 degree state, the first voltage source is shorted, the second voltage source is shorted, the third voltage source is powered with a magnitude of about 1 and a phase of about 0°, and the fourth voltage source is powered with a magnitude of about √2 and a phase of about 45°,
where at an about 180 degree state, the first voltage source is powered with a magnitude of about 1 and a phase of about 0°, the second voltage source is powered with a magnitude of about √2 and a phase of about 45°, the third voltage source is shorted, and the fourth voltage source is shorted,
where at an about 270 degree state, the first voltage source is shorted, the second voltage source is shorted, the third voltage source is powered with a magnitude of about √2 and a phase of about 45°, and the fourth voltage source is powered with a magnitude of about 1 and a phase of about 0°, and
where the 0 degree state, the 90 degree state, the 180 degree state, and the 270 degree state cause the circular disk to radiate with a cardioid pattern.
