EMP Shielding Effectiveness and MIL-STD-285

Abstract

The relationship between electromagnetic-pulse (EMP) shielding effectiveness and MIL-STD-285 is investigated analytically. It is found that measurements carried out in the manner prescribed by MIL-STD-285 using small cw dipole and loop sources located at fixed relative positions 12 in. from the walls will give upper and lower bounds for the EMP (plane wave) shielding effectiveness of any metallic structure at all frequencies of interest (100 to 10 to the 8th power Hz). Upper bounds are provided by dipole measurements and lower bounds by loop measurements for each EMP frequency corresponding to a frequency employed in MIL-STD-285.
