A pulse method for measuring the minimum shielding effectiveness of enclosures

This paper reports a pulse technique for measuring the shielding effectiveness (SE) of enclosures, without the use of an anechoic chamber or an open area test site (OATS). Experimental results are presented and compared to those of the conventional frequency domain method using an anechoic chamber. The results obtained from the pulse method are in good agreement with those of the frequency domain method. The pulse method is demonstrated to be a practical means of measuring enclosure SE, as well as an independent means for cross-checking outcomes from other measurement schemes, because it does not require site calibration.
