Abstract In this paper, the wave propagation in the air coupled composite laminate is studied. The amplitude and phase of the transmission coefficient along with frequency under any incident angle was solved and calculated by the potential function method from the fundamental wave equation with the air-solid boundary condition. The experimental platform was established to measure the transmission coefficient of any incident angle based on MATLAB. Simultaneously the transmission coefficients of composite samples were measured and the experimental results agreed well with those of theoretical calculations. Therefore, the validity of the proposed theoretical solution of the air-coupled wave propagation and the experimental measurement technique are demonstrated.
