内容記述 | Propagation of waves through various kinds of intervenient boundaries is systematically investigated in some simple models, namely the first and second order discontinuities and the perfectly continuous medium. The moduli of transmitted and reflected waves vary between maxima and minima with certain frequency intervals for the first order discontinuity and tend from one value to another for the second order discontinuity with increasing frequency. For the perfectly continuous medium, those vary monotoni- cally. It is necessary to observe the wide band spectrum of the reflected waves to discuss the nature of the boundary. The apparent phase velocity is determined from the phase of the complex transmission coefficient. It is faster in long period waves than in short ones. | |||||
