Summary:This paper proposes a simple electric and magnetic field shielding evaluation method of board level shield can using Transverse Electro-Magnetic cell (TEM cell). Small sized electric and magnetic probes (antennas) are installed on the top of a TEM cell with and without shield can below the probe, and 3-port S-parameters are measured, which are used to calculate the electric and magnetic dipole moments of the probes transferred to the other two ports in the TEM cell. The calculated data effectively evaluated the shielding effectiveness of the shield cans with various ventilation holes in both electric field and magnetic field, separately. Finally, the measured shielding effectiveness was validated by numerical simulation and thus reliable results were obtained.
