The effect of compressibility on the growth of instability modes in a plane free shear flow was studied in this work. The linear disturbance equations of compressible plane free shear layers are solved using a direct spectral method. The mapped spectral method (mapped Fourier method) for the free shear flow of the unbounded boundary conditions was employed. The eigenfunctions satisfy the homogeneous Dirichlet boundary conditions at infinity. Numerical results reveal that oblique modes (3-D modes) are significant in the mixing layer as the convective Mach number Mc increases. Above Mc=0.6, the most unstable mode and also its two subharmonic modes are oblique waves. The fundamental and subharmonic eigenfunctions at Mc=0.8 are presented in this paper. The eigenfunctions structures are affected by the convective Mach number.
