Dear Chi-Fang Huang
You may wish to look on our website
0000,0000,ffffhttp://www.polar.co.uk
which
will enable you to download a version of the current version of
our controlled impedance calculator.
We do not know of any equations for buried differential stripline
and as a result of this we are doing some pure R & D in
conjunction with a UK University to derive new equations for buried
stripline structures.
This involves very complex mathematics but we do expect to complete
the work by the second quarter of this year.
For more information you may wish to e-mail Andy Burkhardt, our
Controlled Impedance Product Manager, here at Polar Instruments.
