摘要
从电磁场基本理论出发,提出了一种通过预留Z形缝隙,以"疏"、"堵"结合的方式提高金属外壳屏蔽效能的新思路,力求以更加易于操作的方式来解决金属外壳缝隙处的电磁泄漏问题。并通过实验,初步验证了这一构想。
According to electromagnetic theory, a new approach to suppress the electromagnetic emission by slots is proposed, which suggests forming Z-shape slots in advance to utilize the combination of ＂elimination＂ and ＂interception＂. It is believed that this new approach will be more applicable. The experiments have been implemented to prove this new approach roughly.
