In this article, the M- type four level system under radiation of two control fields and one probe field is considered. By using of dipole approximation and rotating wave approximation methods, the total Hamiltonian of the system is calculated. Next, by solving of the time evolution equations of the density matrix components and using of the relation between polarization and electric field, the real and imaginary parts of susceptibility coefficients of system is obtained. Then by using of real and imaginary parts of susceptibility coefficients of system, the effect of system parameters on the electromagnetically induced transparency in two semi-classical and semi-quantum approaches is investigated.
