For near-field
Noise suppression sheet evaluation system
Intra/Inter ･ decoupling ratio measurement system
(Rda･Rde measurement system)
IEC standard No. : IEC62333-1, IEC62333-2
Catalog No. nss02
Regarding the evaluation method of the noise suppression seat, Japanese team suggested standardizations to IEC in 2003, and it was enacted in May, 2006. ("KEYCOM" participated as a committee member)
"KEYCOM" has commercialized the measurement kit based on this evaluation method.
It is for the evaluation of electric wave absorption materials to use for prevention of oscillation and an anti-EMI measure of a mobile telephone.
The electromagnetic wave is disorderd in the narrow cases, and an electric field and a magnetic field become independent.
As for the electric wave absorption material in such a situation, the electric wave absorption rate in the near field should be large.
It is unnecessary to disarrange the impedance of the circuit.
