Diffraction of Transient Cylindrical Waves by a Rigid Oscillating Strip

초록

This investigation portrays the transient cylindrical wave diffraction by an oscillating strip. Mathematical analysis of the problem is carried out with the help of an integral transforms and the Wiener-Hopf technique. Using far zone approximation, the scattered field is evaluated by the method of steepest descent. This study takes into consideration the transient cylindrical source and an oscillating strip such that both the source and a scatterer have different oscillating frequencies omega(1)' and omega(0)', respectively. The situation under consideration is well supported by graphical results showing the effects of emerging parameters.
