Trace on Trace off

Formula:

Ex(t, z) = E1sin(ωt − βz + δx )
Ey(t, z) = E2sin(ωt − βz + δy )
Etotal(t, z) = x E1 sin (ωt − βz + δx) + y E2sin⁡(ωt − βz + δy )

Introduction:

Amplitude Ex=Amplitude Ey , |δx-δy| = 90 degrees => The phase difference between Ex and Ey is 90 degree
It is a right-hand circularly polarized (RHCP) wave when the phase of Ex leads, and it rotates counterclockwise in the xy plane.
It is a left-hand circularly polarized (LHCP) wave when the phase of Ey leads, and it rotates clockwise on a plane with Z=0.
