i am currently working on shielding efficiency of nanocomposites and i just want to know what would be the most applicable method for EMI SE measurement in the mentioned frequency range for thin films of shielding material.
thank you in advance!
Dear Sir,
there is IEEE standard 299.1-2013 - IEEE Standard Method for Measuring the Shielding Effectiveness of Enclosures and Boxes Having all Dimensions between 0.1 m and 2 m.
Yours sincerely,
Vesna Milutinovic
Dear Farshad,
several methods there are to measure the shielding effectiveness of the materials in the range of frequency from 600 MHz to 4 GHz. For your material, a good method is to use a system of nested reverberation chambers. The procedure is shown in Standard IEC 61000-4-21. However, you can see the attached works as well.
You could also use an anechoic chamber as well, if you have large samples of the material; you can use a fixture for coaxial cable or waveguide, etc., it depends on the material type.
Dear Sir,
the best method is the far field shielding measurement method.
Use please a german VG standard or a IEEE standard with the word
shielding.
All the best
