Complex representation of electric field
One simple way to deal with "i" thing is to use Euler's identity
$$
i = e^{i\pi/2}
$$
so you can write
$$
E_{out2}=\frac{A}{\sqrt2}e^{i(\omega t+ \pi/2)}
$$
I hope it helps

Why do people say the dynamics of quantum mechanics is always linear?
The linearity of quantum comes from The Principle of Superposition and is one of the most fundamental ideas in Quantum Theory.
In the book "The Principles of Quantum Theory" chapter I, Paul Dirac argu …
