Right-circularly polarized traveling wave

The left-handed yellow wave helix shows the traveling wave form. This wave form is said to have negative 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.
