Hi, Peter

I think such a fornula does not exit. Simply speaking, loss tangent
describes the property of uniform dielectric only. Dielectric conductance
(Gd) depends not only on the dielectric but also the (microwave cicuirt)
structures.

Regards.

Hi SI Folks,
I would like to know the relationship between Loss Tangent and Dielectric
loss. In other words, If I know the "loss tangent" at a given frequency for
a particular dielectric what is the formula to convert this into the
Dielectric conductance(Gd) ?

Thanks,
Peter
