Abstract:
In this paper, the scattering of SH wave by the structure surface with multiple semi cylindrical medium inclusion is studied by using a function of complex variable and a multi polar coordinate method. The so called scattering wave function and the standing wave function in the neighborhood of the multiple semi cylindrical medium inclusion are formed. Using the moving coordinate system,the boundary condition and connection condition can be satisfied. So the condition question may be solved by an infinite set of algebraic equations. Finally, as an example, the scattering of SH wave in the neighborhood with two same semi cylindrical medium inclusion is calculated partially. Numerical results show that the influence of the inclusion on the displacement is remarkable.
