Radio Frequency Interference (RFI) Shielding Principles
www.kriegerproducts.comShielding Effectiveness (SEdB), or attenuation (dB). Shielding effectiveness can be calculated using the following equations. SE dB = 20log H 1 /H 2 (dB) Where: H 1 is the Magnetic Field (µA/m or µT) detected without a shield H 2 is the Magnetic Field (µA/m or µT) detected with a shield between the noise source and sensitive environment SE ...
Understanding Shielded Cable - Mouser Electronics
www.mouser.comineffective shielding. The cable shielding and its termination must provide a low-impedance path to ground. A shielded cable that is not grounded does not work effectively. Any disruptions in the path can raise the impedance and lower the shielding effectiveness. Practical Guidelines for Effective Shielding 1.

www.roxtec.comElectromagnetic shielding Roxtec also provides solutions for cables going in or out of electro magnetically sealed enclosures. The seals are tested to a minimum of 18GHz to prove the shielding effectiveness. Transfer impedance from cable shield to …
Rule-of-Thumb for Calculating Aperture Size #154 - Laird Tech
cdn.lairdtech.comThe shielding effectiveness of an aperture, and ultimately of an enclosure itself, is generally a function of the size of the largest aperture in the enclosure. Enclosure can be defined as anything from a PC board shield to a shielded building and everything in between.
