谐振

The general theory of the electromagnetic resonance and electrical properties of the dielectric materials are simply discussed in chapter 2 in order to cite them in the latter chapters. The two kinds of test techniques of the complex permittivity of the dielectric materials with the low or high permittivity are discussed in chapter 3 and chapter 4 respectively, where the author's creationary work is emphasized particularly.
