SUMMARY

Application of the Floquet theorem and the matrix propagator method reduces the problem of the plane wave propagation in a periodically layered anisotropic media, to analysis of the properties of stationary envelopes of different wave modes propagating up- and downwards. We analyse the interchanging of stop- and pass-bands and their structure at low frequencies for a periodically layered medium with monoclinic symmetry. The analysis shows the effect of interaction between P,S1 and S2 wave multipliers for stop- and pass-band structure and gives insight into the wave propagation in vertically heterogeneous anisotropic media which is important in modelling and interpretation of seismic data.

多层周期性单斜介质中低频P，S1和S2波之间的相互作用

概要

Floquet定理和矩阵传播器方法的应用减少了平面波在周期性分层各向异性介质中传播的问题，从而分析了不同波模向上和向下传播的静止包络线的特性。对于单斜对称的周期性分层介质，我们分析了低频的阻带和通带的互换及其结构。分析显示了P，S1和S2波乘子之间的相互作用对阻带和通带结构的影响，并深入了解了波在垂直非均质各向异性介质中的传播，这对于地震数据的建模和解释很重要。
