The performance of synthesized plane wave sound field is affected by the evanescent contribution of the transfer function and incidence angle of plane wave. In this paper, transfer function is modified by using the rectangular window in wave number domain to eliminate the evanescent sound field. With fixed plane wave incidence angle and spatial sampling interval of secondary sources, the influence of windowed transfer function and plane wave incidence angle on synthesized plane wave sound field were analyzed under the anti-aliasing condition. Simulation results demonstrate that modified transfer function can improve the performance of the synthesized plane wave sound field when the plane wave frequency is smaller than anti-aliasing frequency for a given plane wave incidence angle.
