有耗媒质 meaning in Chinese
lossv medium
Examples
- Under some conditions , although for passive materials , when a plan wave incidents to the interface between a layered lossless material and a layered lossy material , the reflection coefficient of electric field may be greater than unity
在某种条件下，即使在无源媒质中，电磁波在有耗媒质和无耗媒质的交接面上，其组合反射系数可能会大于l 。 - A new standpoint produced from the study is that the guided wave system in the oil well is different from the normal circular wave guide , as the fluid is a conductive medium , and it allows the higher or lower frequency waves to propagate
通过研究提出了由于井内流体为有耗媒质，油井构成的导波系统不同于一般的圆波导，可以传播高频或低频电磁波的新观点。 - Secondly , two applications of gpml abc in modeling pulse radar are shown : one is detecting pipeline underground , and the other is its application to highway technology . thirdly , with back - projection algorithm , we have formed the image of tree - trunks . in summary , the application of fdtd in uwb fopen so far is impressive
然后，对适用于有耗媒质的gpml边界条件的应用开展了深入研究，对脉冲雷达探测地下管道和测量高速公路沥青层厚度进行了fdtd算法模拟。 - First , the fundamental theory of the basic fdtd method and its application in the analysis of the electromagnetic properties of infinite planar periodic structures is summarized . the basic ideas of the auxiliary fields fdtd method is expressed and generalized to the situations of the 2 - d periodic structures , to lossy media , and to the curvilinear coordinate . the shortcoming of this method in the management of conformal grids is pointed out
首先总结了fdtd方法的基本理论及其在周期性结构电磁特性分析中的应用，阐述了辅助场fdtd方法的基本思想，把它推广到二维周期性的情况和计算区域为有耗媒质的情况，再进一步推广到曲线坐标系中，并指出了该方法在网格共形处理中的不利之处。 - Expressions in three kinds of perfectly matched layer ( pml ) absorbing boundary conditions is also given . second , the numerical theories of the auxiliary fields fdtd method is studied , including the stability of the differential equations and the numerical dispersive relationship . the stability of two kinds of differential formulations and three kinds of pml is compared , using a straight method depending on the pmax - t graph
更进一步，研究了辅助场fdtd方法的数值理论，对其微分方程、差代方程的稳定性进行了分析，比较了有耗媒质中的两种差分格式和三种理想匹配层中的差分格式的稳定性，提出了一种通过p _ ( max ) - t曲线判定稳定性并求出稳定性条件的直观方法，并导出了该方法的色散关系式。
