采用谐振腔微扰法的NiZn铁氧体介电常数测量
Measurement of complex permittivity of NiZn-ferrite by resonant cavity perturbation method
摘要
Abstract
The cavity perturbation technique has been widely used for microwave dielectric properties measurements. It has the great advantages of convenient experimental measurement, small sample dimension, and simple computation formulas. It has a good application value in approximate calculation frequency and the quality factor of resonant cavity, material dielectric constant. The complex permittivity within microwave frequency band of NiZn ferrite was measured by resonator cavity perturbation method. The imaginary part e" and the real part e' of the dielectric constant were obtained, and the effects of content of Ni and Zn on complex permittivity were analyzed.关键词
