Diffraction of a plane acoustic wave by a semi-infinite soft cone with cut apex

Acoustic bulletin, Vol. 16 ¹ 4, (2013-2014) p.33-41
The paper deals with solving the problem on diffraction of a plane acoustic wave by a truncated semi-infinite soft cone in its axial irradiation. The problem is solved in terms of the velocity potential of a diffracted field by the method of partial domains. Using the field matching technique, the summation equations are reduced to the infinite system of linear algebraic equations of the second kind by means of analytical regularization procedure. The obtained system allows the solution with a desired accuracy using the reduction method. Field characteristics are studied at different geometrical parameters and frequencies. The reliability of numerical data is confirmed by their comparison with the results obtained by other authors for some particular cases.
