The method for determining the equivalent parameters and shielding factor of thin-walled cylindrical shells-screens.

Abstract

The cylindrical shell-screen is replaced by an electrical circuit with equivalent parameters M, re and xe. depending on the current distribution along the height of the screen, which is determined from the condition of equality at an infinitely large current frequency in the source of the magnetic fluxes of the source and the screen, penetrating any cross-section of the screen. A technique is proposed that makes it relatively easy to determine the equivalent parameters M, re, and xe of limited, unclosed thin-walled cylindrical shells-shields bounded by the sources in the longitudinal magnetic fields. According to equivalent parameters, it is easy to calculate the current, losses and shielding factor S of unclosed cylindrical shells-shields. Ill. 3, Bible. 1.
