Abstract :
The effectiveness of an imperfectly-conducting cylindrical shield of small cross section depends on both the attenuation through the metal wall of the externally maintained field and the amplitude of the current that is induced in the cylinder. When the length of the cylinder, which behaves like a linear scattering antenna, approaches a resonant value, the currents induced in the walls and the field inside the tube are relatively large. Under these conditions, large currents may be induced in a thin dipole placed coaxially within the shield.
