Abstract: Here is presented the calculation of the dynamic electrical conductivity of fully ionized, strongly coupled plasmas as a function of the external electric field frequency $omega$. The calculations are based on the the formula for the energy-dependent collision frequency which is determined by means of the Green function theory methods, as a sum over the Matsubara frequencies. The domain of extremely high electron density: $10^{21}leq{n}_{e}leq10^{24}extrm{cm}^{-3}$, and for the temperature varying from $10extrmkK$ to $1.000extrmkK$ was examined. The real and imaginary parts of the conductivity for every electron density are presented in the generalized Drude-like form as a two-parameter function of the frequency $omega$ in the region $0<omega<0.5omeg{a}_p$, where $omeg{a}_p$ is the plasma frequency. A good agreement between the obtained results and the existing theoretical and computing simulation data is shown.
