Determination of loss tangent and its frequency dependence for different equivalent circuits that describe dielectric losses: (A) simplest representation; (B) more complicated cases. However, to describe losses in dielectrics, this characteristic is inconvenient, as angle φ usually is a very little ...

The data on dielectric properties of Indian rock samples are verylt;br /gt;sparsely reported in the literature. Keeping this in view, we have carriedlt;br /gt;out laboratory measurements of the dielectric constant and loss tangentslt;br /gt;of some samples of sandstone, quartzite, limestone,...
Lumped models that represent a lossy substrate with constant loss tangent over a given bandwidth are presented. Two network representations are given, which are based on the continued fraction expansion (CFE) of a causal network function, and the Debye model. Proposed models are compared with per...

The mechanism of loss in high performance microwave dielectrics with complex perovskite structure, including Ba(Zn1/3Ta2/3)O 3, Ba(Cd1/3Ta2/3)O3, ZrTiO4-ZnNb 2O6, Ba(Zn1/3Nb2/3)O3, and BaTi4O9-BaZn2Ti4O11, has been investigated. We studied materials synthesized in our own lab ...
The optional anneal may partially crystallize the layer, further densify the layer, or both. The reduced number of defects and the increased crystallinity reduce the loss tangent of amorphous silicon dielectrics for superconducting microwave devices.Frank GreerAndy SteinbachWenxian Zhu...

Loss measurementDielectric loss measurementThe investigation of the dielectric properties is generally performed using either ac or dc voltages. As the ac and dc properties often differ significantly, it is of practical importance to study the properties under simultaneous action of both ac and dc ...
