Left-circularly polarized traveling wave

The right-handed yellow wave helix can both be understood as rigidly rotation about the yellow equilibrium x-axis
or moving rigidly along the axis with velocity omega/k. This wave form is said to have positive helicity. The geometric
algebra expression for it is:

q_omega (x,t) = a_omega exp(**i**(omega t - kx)),

with a_omega the constant vector amplitude in the **i**-bivector plane.
The set of green vectors shows how a vector at x=0 would rotate with varying t.
