Thus, the complementarity between the relative permittivity and permeability can be efficiently tailored by mixing CNTs with [Fe.
To see how significant the space or vacuum polarization is, we plot, in Figure 2, the relative permittivity [[epsilon].
The dimensions of a trace or via, plus the relative permittivity, [epsilon]r, of the PCB material, determine its inductance and capacitance.
The designed antenna can be further miniaturized using one of the following approaches: 1- using higher relative permittivity for the substrate material; the designed frequency scales with the square root of the dielectric constant, so as the dielectric constant increases, the resonant frequency reduced.
at the real values of the relative permittivity of the semiconductor screens material in the insulation system of high-voltage XLPE cables (at least 100), the maximum tg[delta] approaches to the regulatory value (tg[delta] = 0.
The foam material in the previous studies is replaced by a dielectric substrate of relative permittivity 2.
Its additional qualities of low temperature coefficient of frequency, relative permittivity, and low electrical loss allow a range of medical applications, including microwave therapy and medical imaging, to be addressed.
These sensors use the high relative permittivity of water (relative permittivity ~80 for water, ~3-5 for soil solid and ~1 for air) to infer the volumetric water content (0) of soil (Hanson and Peters 2000).
Here DMSO was selected as the additive of PEDOT:PSS to adjust the conductivity, relative permittivity, and surface tension of PEDOT:PSS inks.
infinity]] is the relative permittivity at high frequency limit, and [chi] is the electric susceptibility.
