Coaxial cables impedance matching

Coaxial cables impedance matching

Coaxial cables impedance matching

I have to connect together two air dielectric coaxial cables with same external diameter, but different diameter of the inner conductors.
My question is: how can I simulate this kind of connection?
I have a microwave CAD but unfortunatly the program doesn't work on this kind of component (I think is possible simulate it with a capacity, but I don't know how to relate the capacity to the geometrical dimension of the lines).
Could someone help me?
Thank you.

RE: Coaxial cables impedance matching

Try using ANSOFT HFSS Which can handle all these kind of problems.

RE: Coaxial cables impedance matching

Dear antenna
I think it is more useful to solve this problem analytically & use CAD's software for complicated problems so you can simulate 2 coax. line that can guide TE & TM mode in addition to TEM modes & then marginal conditions ...
