Abstract: Propagation of waves from a source located on a free surface inside a circular conical horn is studied within the framework of a three-dimensional axisymmetric acoustic approximation. The horn axis is assumed to be orthogonal to the free surface. The influence of the horn geometry on the efficiency of radiation focusing in an arbitrary circular cone is studied. Criteria, objective functions, and control parameters for efficiency estimations and horn optimization are proposed. A method of optimizing the radiating system consisting of the source on the free surface and the horn on the basis of the problem geometry is developed. Geometric parameters ensuring the best focusing of radiation of the source-horn system in a circular cone for an arbitrary transmission angle are determined.
Keywords: horn, oscillations near the free surface, focusing, acoustic source, seismic source, vibroacoustic source, radiation direction.
