WebSo, an electric field of the form E ( z, t) = E 0 e i ( k z − ω t + ϕ 0) + c. c. = 2 ⋅ E 0 cos ( k z − ω t + ϕ 0) indeed describes a real/physical wave. Of course, while doing the maths it may become cumbersome to carry around the c.c. term through a series of equations, and so it is dropped (but implicitly, it is still there).
