I have a problem and I would appreciate if somebody can help me threw
it.
I am trying to calculate the amplitude of a picoseconds pulse after has
propagated a distance within a superconductor. The following steps were
used by the author of a paper which results I am trying to re produce.
As you all know conductivity is complex in a superconductor.
Using the complex conductivity the surface impedance can be calculated.
Quote: From there we can calculate the impendence.
Using the above the propagation constant is calculated. Where my poor
maths suggest that is a complex number.
Finally this propagation constant will be used to calculate the voltage
of a picoseconds pulse propagating within a superconducting planar
strip line.
I will get a complex number as a result.
My question is, can I use the real part only as my result???
Have any of you come across something similar??? |

I will try this. I will let you know the results.
Thanks

In classical physics, only the real part (or the imaginary part) are
physically meaningful. This is in contradistinction to quantum physics
where only magnitudes are meaningful.
