Abstract
This paper examines electromagnetic leakage path of small shield cans employed in mobile devices such as smart-phones by using numerical simulation and analyzes near-field coupling due to each of the leakage electric and magnetic fields by using IC-stripline method. From the results, it is confirmed that the leakage from the apertures or slots on the top of shield can is dominated by magnetic field, whereas the leakage from the seam on the side of shield can is mostly caused by electric field.
