For example, a chassis door that is not bonded to the chassis may act in this manner. Placing a wire connection between the door and the chassis may provide a low resistance and meet the safety requirements, but the high frequencies may radiate if the ...
WebAn ungrounded shield does work as a shield in blocking the E-field component of a EM wave as long as the shield is continuous. But it does so by means of attenuation (the conductor depth must be greater than the skin depth) and redirecting the wave as current around the volume that the shield encloses.
