[SI-LIST] Answer: Transfer Impedance of Rectangle Power Plane Pairs

Dear All

Last week, I proposed a question about transfer impedance of rectangle power 
plane pairs. It stated that the simulation of double sigma function does not 
agree with the measurement result.

Now the reason has been found. The double sigma function does not consider the 
effect of the copper. When the copper is changed to PEC, the results agree to 
each other very well.
