摘 要: 研究电磁波(EM波)在土中的传播特性,必须获得如介电常数和磁导率等基本电磁参数· 在麦克斯韦方程组的基础上,提出了等效模型来计算土体介电常数· 利用该模型的计算结果与实测数据符号很好,可以为利用电磁波法测量土体含水量。 The fundamental parameters such as dielectric permittivity and magnetic permeability are required to solve the propagation of electromagnetic wave(EM Wave)in the soil.Based on Maxwell equations,the equivalent model is proposed to calculate the dielectric permittivity of mixed soil.The results of calculation fit the test data well and will provide solid foundation for the application of EM wave in the soil moisture testing,CT analyzing of soil and the inspecting of geoenvironment.
