Transient processes in a gas/plate structure in the case of light loading

The problem of a pulse excitation in an acoustic half-space with flexible wall described by thin plate equation is studied. solution written as double Fourier integral. A novel technique estimation this integral developed. surface integration deformed such way that the integrand exponentially small everywhere except neighbourhoods several ‘special points’ provide field components. Special attention paid to associated coincidence point branches dispersion diagram medium and plate. This shown be harmonic wave finite duration.
