On the parameter optimization of coaxial lines with ferrite rings

The problem of parameter optimization of coaxial lines including two layers of insulators and an inside ferrite layer is considered. The choice of electrotechnical parameters for coaxial lines are presented. Basing on the expressions for optimal values of electrical intensity and geometry, it is shown that the optimal construction could not be realized for all parameter values. The graphs given allow to choose practically possible values, these simplify constructing the lines filled partially with ferrite
