I have a simple eigen function such as [itex] \varphi = Ae^{ik_{1}x} + Be^{-ik_{1}x} [/itex]

This is complex form which means we can't draw this function on real coordinate.

How can i draw this function? just By taking out real term of complex function?

Second question is what does transmission coefficient means. What exactly i want to know

is how to know amplitude of transmission wave from transmission coefficient in potential

barrier problem? For instance, in problem such that x < a, v = 0 and x >= a, v = c,

Transmission coefficient [itex] T = |\frac{C}{A}|^2\frac{k_2}{k_1} [/itex]

But This expression contains absolute value of ratio A to C, So i'm not sure that This

expression indicate real transmission amplitute C when we know Incident amplitute A.

More over, i'm confusion that whether amplitute of wave can be complex number.
