摘要
微扰法测量2450MHz频率下微波等效体模的复介电常数,取得了较好的结果。这对于微波等效体模模拟生物组织的研究具有重要的意义。
It is the measurement of high-loss dielectric to measure the permittivity and conductivity of biologic tissue.But now it is difficult to measure them accurately.Good result is got by measuring complex permittivity of phantom model at2450MHz using perturbation method,which is meaningful for the research on biologic tissue simulation by phantom model.
