摘　　要：从Maxwell方程出发 ,导出了平面波入射到半无界均匀各向异性媒质时电磁场的相互关系 ,根据有耗媒质应满足波传播条件和玻印廷矢量散度的实部应小于零 ,推得了无源有耗各向异性材料参数应满足的条件 ,论述了该有耗判别准则的充要性 。Based on Maxwell′s equations, the relationship of electro and magnetic fields in half infinite anisotropic medium with a plane wave incidence is delivered. As the real part of the divergence of Poynting vector for lossy medium must be less than zero and the propagation condition must be satisfied, the sufficient and essential judgement criterions, which the sourceless lossy anisotropic medium parameters must satisfied, are obtained. The criterions are also certificated theoretically. These provide hard theoretical basis for studying medium parameter reconstruction.
