损耗介质界面上垂直入射的平面波的区分,取决于界面两边的密度和吸收波散对。对于一个已知能量损耗的模型,规定了速度和吸收系数(吸收波散对),它们随频率而变化。介质吸收波散对之间的差异可以归因于同一模型中的不同参数或两个不同的模型。对于一个已知吸收波散对之间的差异,其幅度和频率与反射系数的关系和相位变化能够计算出来。所用的实验室及野外数据与由几个介质模型预测的速度,吸收系数,对数衰减量 The distinction of a plane wave perpendicularly incident on a lossy dielectric interface depends on the density and absorption wave pairs on either side of the interface. For a model of known energy loss, the speed and absorption coefficients (absorption wave pairs) are specified, which vary with frequency. Differences between wave pairs of dielectric absorption can be attributed to different parameters in the same model or to two different models. For a known difference between wave absorption pairs, the relationship between the amplitude and the frequency and the reflection coefficient and the phase change can be calculated. The laboratory and field data used were compared with those predicted by several media models, absorption coefficient, logarithmic decrement
