Taking into account of electron displacement polarization and using the resonant binding electron model,the expression of relatively dielectric constant of metal is derived,then two important case of low frequency and high frequency are discussed,at last a expalanation on dielectric constant of metal ...
We calculate the effective dielectric constant of a composite medium containing metallic particles, characterized by the Drude dielectric function . The value of is so high that the factor |2πrλ| is of the order of unity. We compare our results with those given by the Bruggeman mixing rule...

(separation of charge) is not complete. Under such conditions, thedielectric constantappears to be less than that observed in a direct-currentcircuitand to vary with frequency, becoming lower at higher frequencies. During the alternation of polarity of the plates, the charges must be displaced ...
Copper is expected to alleviate the resistance problem for next few generations, the capacitance problem is expected to be alleviated by reducing the dielectric constant of intermetal dielectric that isolated conducting lines from each other... H Zhou 被引量: 0发表: 2002年 加载更多研究...
Dielectric dispersion: This is the variation of the dielectric constant with the frequency of the applied electric field. It occurs because different types of polarization mechanisms have different response times to the changing field. For example, electronic polarization, which involves the displacement ...

If after cooling, the charges are immobilised, the dielectric will behave as an electrical equivalent of a permanent magnet. This is known as an electret (thermoelectrets in this case). An electret loses its volume charge exponentially but with a very large time constant (order of 100 years...
