[SI-LIST] Re: Interplane capacitance efective frequency range

We have a lot of experience and back round info for inter plane
capacitance, including some of our collaborations with Istvan,  on our
website under White Papers.

If you have specifc design or application questions you want to ask off
line, contact us.. We have impedance characterized from Mhz to GHz for
various dielectrics.

Rodrigo, the formula for plate capacitance is:

 

e0*eR*Area / Height

 

The frequency range issue is complicated by resonance and wave modes, 

and what if anything the design does about them.  Istvan has some of the


best papers available on this subject on his web site:
