Abstract:
Apertures in a enclosure of electronic equipment are main channels of radio disturbance radiated.Based on FIT,this paper simulates electromagnetic field for Shielding Efficiency,applied on typical radiated emission frequency(30 MHz～1 GHz),their shilding efficiencies are computed and compared.The simulation results show that SE for E-field and H-Field are different under the same area and different shapes.It is helpful for engineers who are designing EMC shields.
