Hello everyone. I got my raw data from VNA in the form of S11 (log), S11( Deg)....and so on. if you guys please assist me in that issue, I'll be thankful to you.
Note: I've attached my raw data excel form for your references.
Regards & Thanks
Your S21 and S12 are about -13.6 dB
To turn this into a power ratio you do 10^(dB/10). Don't forget the negative sign.
I don't know how you want to express the shielding efficiency.
Multiply the power ratio by 100 to get the percentage that got through, which I presume is the shielding efficiency in %. Otherwise the shielding efficiency in dB is probably just the S21 or S12 in dB.
Thank you so much Malcolm White for your valuable answer. I was confused by the angle but now i got some idea from your answer.
Is that is 10^(dB/10) or 10^(dB/20)? please correct me if i am wrong.
The power ratio is 10^(dB/10). Electric field ratio is 10^(dB/20).
The S parameters are complex numbers 10^(dB/20)*cos(degrees)+j10^(dB/20)*sin(degrees)
