in electromagnetics port, we can define linear polarized light by use Ex=1, Ey=0, and Ez=0; or define circularly polarized light by Ex=1, Ey=i, and Ez=0. can we define nactural light by Ex=1,Ey=1, and Ez=0?

This gives 45° linear polarization. What is nactural light?

If you mean natural light, then I suspect you mean unpolarized light. For that, you might consider using the scalar wave equation in the physics/math interface, rather than an RF/EM representation. See also https://en.wikipedia.org/wiki/Helmholtz_equation .
