Signal degradation by loss tangent and dielectric constant can be easily assessed by an eye pattern.
This gives rise to the parameter known as the loss tangent " ? " where
The loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis.
Loss tangent determines how much of the electromagnetic energy from the signals in the conductors is absorbed in the board material.
Losses in the dielectric depend on the loss tangent ( tan " ? " ) of the material divided by the wavelength of the signal.
The shear modulus of PDMS varies with preparation conditions, but is typically in the range of 100 kPa to 3 MPa . The loss tangent is very low.
where k is the wavenumber, \ scriptstyle \ eta is the permeability and permittivity respectively and \ scriptstyle \ tan \ delta is the loss tangent of the dielectric.
Once the complex permittivity of the material is known, we can easily calculate its effective conductivity \ sigma _ e and dielectric loss tangent \ tan \ delta as:
Higher " Q " factors can be obtained by using low loss tangent dielectric materials for the substrate such as quartz or sapphire and lower resistance metals such as gold.
RF bandpass filters can be used to increase FBAR resonators have superseded distributed RF bandpass filters based on transmission line resonators, printed on substrates with low loss tangent, or based on waveguide cavities.
