碩士 === 國立臺灣大學 === 電機工程研究所 === 84 === The main point of this paper is the measurement of the attenuation of the microstripline that contains composite material and finding a method for estimating the conductivity of the composite material.The composite material that is under test is put under the dielectric slab of the microstripline ,regarded as the second medium .The attenuation constant of composite material is estimated by the S parameter of the two layer medium microstripline .It is the experimental value.The frequency range of the measurement is 50MHz-10GHz.By numerical method computing the attenuation of composite material of different conductivities ,we can compare the experimental values with the theoretical values then estimate the conductivity of of the composite material.
