We present the extension of non-dipole strong field approximation that incorporates few-cycle laser pulses. We investigate the non-dipole effects of strong-field ionization. To do so, an atomic gas target is irradiated by circularly-polarized mid-infrared few-cycle laser pulse. To the end, we compute the photo-electron momentum distribution of argon and deduce the peak shifts of transverse electron momentum distribution in the laser propagation direction. Compared to recent work by [Phys. Rev. A 99,053404(2019)], we demonstrate a better agreement between theory and experimental investigations.
