The Study on Complex Dielect Constant of Ni/Polythene Composites

This paper studied the complex dielect constant of a shielding material-Ni/polythene composites in the frequency range from 50MHz to 1000MHz. Results showed that when Ni mass content is below 70%,the influence of Ni content and frequency on was very little;When Ni mass content was above 70%,in different frequency range,the Ni content's influence on was different;When Ni mass content was below 80%,the influence of content and frequency on was not notable;when it was above 80%, raised rapidly with the increase of Ni content,and decreased with the increase of frequency.
