Research On Shielding Effectiveness Testing Method On Cable Coupling

In electromagnetic compatibility field, calculating the shielding effectiveness of shieldbody is a important subject. The electromagnetic environment worsens the electronicequipment and system of continuous miniaturization sharply, which makes the small shieldshielding effectiveness measurement method more and more.The paper researches a new kind of measurement method in the shielding effectivenesson cable coupling, which is based on the actual problem. First of all, gives the shielding of theconcept and the shielding effectiveness of the theoretical calculation; Then introduciesthrough the comparative study of domestic and foreign to shield the shielding effectivenessmeasurement method, this paper introduces several common for small shield the shieldingeffectiveness of the proposed method of measurement, and the method of principle andadvantages and disadvantages are analyzed, and through the simulation gives a practical smallshield shielding effectiveness is given; Then the electromagnetic field on cable coupling wayand electromagnetic coupling cable theoretical calculation are analyzed, and finally realize thecable coupling way for shield shielding effectiveness of the simulation analysis.The paper has given model and data can be used as reference for the design of theactualization of further engineering, has certain theoretical significance and practical value.
