Query: About attenuation of videopulse in nonlinear transmission lines with
  ideal dielectric   The attenuation of the video pulse with monotonically increasing input
voltage in a transmission lines with an ideal dielectric can be characterized
by "ohmic" voltage drop $U_\sigma$ along the electrodes with finite
conductivity. The exact analytical formulas for the calculations $U_\sigma$ in
coaxial and strip lines with and without taking into account the strong skin
effect have been obtained. These formulas do not depend on the dispersion and
the degree of nonlinearity of the dielectric and therefore is suitable for
evaluating of shock electromagnetic waves attenuation
