Abstract: The ratio of the electric and magnetic form factors of the proton ${G}_{{E}_{p}}{/G}_{{M}_{p}}$, which is an image of its charge and magnetization distributions, was measured at the Thomas Jefferson National Accelerator Facility (JLab) using the recoil polarization technique. The ratio of the form factors is directly proportional to the ratio of the transverse to longitudinal components of the polarization of the recoil proton in the elastic $\stackrel{\ensuremath{\rightarrow}}{e}p\ensuremath{\rightarrow}e\stackrel{\ensuremath{\rightarrow}}{p}$ reaction. The new data presented span the range $3.5<{Q}^{2}<5.6{\mathrm{GeV}}^{2}$ and are well described by a linear ${Q}^{2}$ fit. Also, the ratio $\sqrt{{Q}^{2}}{F}_{{2}_{p}}{/F}_{{1}_{p}}$ reaches a constant value above ${Q}^{2}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}2{\mathrm{GeV}}^{2}$.
