phase from CST (De-embed)

cst deembed

According to the following discussion at




The Sij( phase) from CST shoulb be de-embed in order to get correct results . Could anyone give more detail how to deembed Sij from CST? Or any person can give some comments on the retrieve process?

Thanks very much.

what is de-embedding in cst

I do not believe the phase computations of reflections Sii. Probably the software is updated now. My past experience is bad with the Sii phase values. It never matched with the measurements.

Hi, helio1972, thanks very much and it is very helpful.
About the question by kspalla, I think the simulation results from CST are in good agreement with our experimental results, and so I think we can believe it. But if you have more comments about it, just go ahead. We may find what happen.

Best regards!
