Transmission of narrow sound beams in nonlinear environment (Նեղձայնային փնջերի տարածումը ոչ գծային միջավայրում)

Համառոտագիր

In the paper we consider the problem of the transmission of limited sound beams. The transmission of such beams is described by a nonlinear partial differential equation. In the paper we solve this equation by the latticecharacteristics method. Some numerical results are obtained for a special case.
