Nanocomposite dielectric materials include inorganic nanoparticles in a polymer base, which together have high dielectric constants due in part to the inorganic nanoparticles while retaining much of the processability of the base polymer.
Therefore, it is possible to calculate dielectric constants for liquid paints from their formulas and knowledge of the [epslion] values of the components.
Analysis of the Simulated Dielectric Constants. The soil soluble salt in the groundwater can rise to the surface as water moves through capillary action in the soil.
In their model, the authors did not consider the fringing filed effect on the antenna parameters and the effect of radius of curvature on effective dielectric constants.
Corresponding dielectric constants were also calculated based upon Maxwell's rule of mixtures [31] (see, (3)) and Lichtenecker's logarithmic mixing model [32](see(4)).
Simulated reflection coefficients of homogeneous and non-homogeneous dielectric constants are shown in Table 1.
From the sensor's viewpoint, the dependency of the read range on EM properties of CMs near or in contact with tags can be employed as an approach to determining quality of CMs through their estimated dielectric constants. RF tag performance is affected by many factors, including EM properties of objects near or in contact with tags [10, 11].
It consists of two parallel metal plates that contain in between two different media of dielectric constants [[epsilon].sub.r1] and [[epsilon].sub.r2] respectively.
These new materials are important because they have high dielectric constants beneficial for advanced semiconductor transistors.
It requires no field calibration, withstands high temperatures, and works with materials having a wide range of bulk densities and dielectric constants. It is compatible with the company's newest SiloTrack Version 3.5 PC-based inventory-management software.
First, the experiment was performed using a series of fluids of known relative dielectric constants, then numerical simulations were carried out and confirmed by soil sample test with varying operating frequencies and probe lengths.
Using proprietary substrates that feature dielectric constants between 4 and 152, and a dielectric loss tangent as low as 0.00015 customers can specify microwave filters and high Q resonators.
