Abstract :
A simple shielding evaluation method of small shield cans using a transverse electromagnetic cell and a specially designed test printed circuit board is proposed. Numerical modelling of the measurement setup using a commercial three-dimensional electromagnetic field simulator is also introduced to verify the measurement. From measurement and simulation, reliable results for shielding evaluation of the shield cans were obtained.
