For microwave dielectric ceramics, the relative permittivity (εr) is low to reduce the signal transmission delay, the quality factor (Q×f) is high to reduce the dielectric loss (tanδ = 1/Q) of transmission, and the temperature coefficient of resonant frequency (τf) is near zero to ...
diameter. The outer shell is 10.1 mm in diameter. A potentialV0 = 50 V is connected across the two shells so that the positive pole of the battery is connected to the inner shell. The space between the shells is filled with a dielectric with a relative permittivity of 2.25. ...
The relative permittivity \(\varepsilon \) of each layer can be estimated using the Hashin-Shtrikman bounds theory; these permittivity values should be different for each layer12. The relative permittivity of the layers depends on the grain connectivity ratio (%) and top and bottom limits, ...
A dramatic improvement in the dielectric and electrical properties has been observed in ceramics of 0.8BaTiO-0.2Bi(ZnTi)O through the introduction of Ba vacancies. It possesses a high relative permittivity (ε> 1150) along with a low die... N Raengthon,DP Cann,J Roedel - 《Journal of the...
Here, the excellent microwave dielectric properties are reported in H3BO3 ceramics with the molecular crystal structure, whose permittivity (2.84) and density (1.46 g/cm3) are record-low among the low-loss ceramics. The ultra-high Qf value of 146,000 GHz (or the ultra-low dielectric loss of...

By surrounding the lifting line with a material volume, the P-TGR of the grounding system is greatly reduced. The effect of the surrounding volume conductivity and relative permittivity on the P-TGR is also tested. Second, the rectangular surrounding material volume is shielded wi...
