内容記述 | A plane pulse passing through a heterogeneous medium consists of two parts: an undisturbed and a disturbed pulse. The undisturbed pulse transmits without changing its form. On the other hand, the envelope of the disturbed pulse is of a function sin x/x, its maximum appears to be delayed after the undisturbed pulse, and the period of its carrier wave is π・(average velocity)/(wave length of the structure). This disturbance is interpreted as scattering by the heterogeneity of the medium. | |||||
