Thus, the complementarity between the relative permittivity
and permeability can be efficiently tailored by mixing CNTs with [Fe.
Calculation of the effective relative permittivity
(an auxiliary parameter):
To see how significant the space or vacuum polarization is, we plot, in Figure 2, the relative permittivity
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.
cm-3 for the developed crystal and relative permittivity
at 1 MHz was evaluated as em = 21.
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
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.
