Abstract

Aperture coupling is the primary way that electromagnetic interference energy into the metal chamber, which would damage the electronic equipment. Articles use FEKO electromagnetic simulation software to analysis the aperture coupling electromagnetic field inside the metal chamber with equal-area different shape (square, circular, rectangular) and the different number apertures . Analysis results showed that: equal-area condition, the round hole chamber has the best shielding effectiveness, multiple hole chamber shielding effectiveness is better than a single hole chamber.
