A new methodology to determine the loss tangent of dielectric planar samples by using electrically coupled resonators is presented. The coupling between the resonators is disrupted by the sample under test (SUT). The proposed methodology is based on the analysis of the equivalent circuit of the ...
and as an indication of changes in quality resulting from contamination and deterioration in service or as a result of handling. The loss characteristic is commonly measured in terms of dissipation factor (tangent of the loss angle) or of power factor (sine of the loss angle) and may be expr...
The dielectric constantfor 5 mm sample was higher than that of the 2 mm. On the other hand, the loss tangentfor 2 mm sample was lower than that of 5 mm YIG filled TPNR. This composite showsthe value of dielectric constant and loss tangent at the X-band. Hence, this research will...
