Quantum Transmission Coefficient
Hello. I have a question, mathematical in nature.
Considering a potential step of height V0 and width a, the amplitude coefficient is
Now the transmission coefficient is
So I need to find the absolute value of this expression. I thought about taking the complex conjugate of the denominator and multiply both the numerator and the denominator by this factor (in order to make the denominator real). but this is very messy.
Is there a simpler way to find the absolute value of this expression?

Much simpler. Take the complex conjugate of both the numerator and the denominator separately. If t = N/D, then |t|2 = N*N/D*D
