Abstract :
The skin and proximity effects in cylindrical and nonmagnetic conductors are considered. The cross sections of these conductors can have arbitrary shape. A procedure is presented for computation of current densities over the sections and an expression for the calculation of the impedances matrix is also developed. The equations are written in a generalized form, which is useful in studying systems of several parallel interacting conductors. Using mathematical software, these two effects can be simulated and the behavior of impedances, losses, and coupling when electrical parameters and geometrical configuration are modified can be analyzed.
