relative permittivity การใช้

• A low relative permittivity allows for higher-frequency usage.
• In an anisotropic material, the relative permittivity may be a tensor, causing birefringence.
• Relative permittivity is a complex-valued; its real and imaginary parts are denoted as:
• The magnitude of these normal vectors is given by the square root of the relative permittivity.
• Besides the relative permittivity, the size and number of layers determines the later capacitance value.
• Relative permittivity describes modification of the speed of electromagnetic wave propagation as well as the wavelength.
• In materials with relative permittivity,, and relative permeability,, the phase velocity of light becomes
• At 205 癈 the relative permittivity falls to 33, the same as methanol at room temperature.
• Relative permittivity is the factor by which the electric field between the charges is decreased relative to vacuum.
• The actual permittivity is then calculated by multiplying the relative permittivity by " ? " 0:
• A modified version of the Curie Weiss law applies to the dielectric constant, also known as the relative permittivity:
• The relative permittivity of a medium is related to its electric susceptibility,, as 1 + ? e } }.
• As established in the previous section, the most important quantity in radiative transfer calculations of sea ice is the relative permittivity.
• Where \ zeta is the zeta potential of the capillary wall, and \ epsilon is the relative permittivity of the buffer solution.
• The theory of the equilibrium relative permittivity, ? ( ? ) of dipolar substances had been developed by Onsager ( 1936 ).
• The extensive hydrogen bonded network in water tends to oppose this alignment, and the degree of alignment is measured by the relative permittivity.
• It is noteworthy for its extremely large dielectric constant ( effective relative permittivity ) of in excess of 10, 000 at room temperature.
• Phys . " reference that includes quantum electrodynamics effects and still states that the linear relative permittivity of vacuum is ( exactly ) unity.
• Thermal motion of the molecules disrupts the hydrogen bonding network as temperature increases; so relative permittivity decreases with temperature to about 7 at the critical temperature.
• Relative permittivity is also commonly known as "'dielectric constant "', a term deprecated in physics and engineering as well as in chemistry.
