八散射波滤波揭示的层次几乎在物理学的各个分支学科中都出现波的问题。我们将研究这些波,但是在此处,将不假定我们已熟悉物理学及微分方程,而只利用延迟、连续性以及能量守恒等一般原理。所得结果将直接应用于声波、水波、薄膜中的光、法线入射的纵、横弹性波、电磁波、传输线、梯形电网络以及其它诸如此类的东西。这些方法不可以用于各种扩散问题。我们的首要目的是解决已知反射系数,计算波场的问题。第二个主要目的是据已知观察到的波,提高计算反射系数的能力。 8—1 反射系数与透射系数考虑两个半空间(地下和天上)。如果一个具有单位振幅的波入射到界面上,就会
The levels revealed by the eight scattered wave filters have wave problems in almost every branch of physics. We will study these waves, but here we will not assume that we are familiar with physics and differential equations, but only use the general principles of delay, continuity, and conservation of energy. The results will be applied directly to sonic waves, water waves, light in films, normal incident longitudinal and transverse elastic waves, electromagnetic waves, transmission lines, trapezoidal electrical networks, and the like. These methods can not be used for a variety of proliferation issues. Our primary goal is to solve the known reflection coefficient and calculate the wave field. The second main purpose is to increase the ability to calculate the reflection coefficient based on the waves observed. 8-1 Reflection Coefficient and Transmission Coefficient Consider two half-spaces (underground and heavenly). If a wave with a unit amplitude is incident on the interface, it will be
