Transmission coefficient for penetration of intense femtosecond laser pulse through ultrathin foils with the thickness of the order of 30–100 nm has been derived using the Vlasov–Boltzmann equation as a function of foil thickness. It is found that this coefficient oscillates resonantly if the transverse (parallel to the foil boundary) electron energy is equal, or larger than the longitudinal (normal to the foil boundary) electron energy.
