An electro-magnetic shield is to be made of galvanized steel with conductivity = 1.74 x 106 S/m, and magnetic permeability HR = 80. The thickness of cold rolled steel is in the following table. Gauge Number Thickness (mm) *f= 150 kHz 8 4.269 9 3.891 10 3.51 11 3.1318 -24 Gauge 12 2.753 14 1.9939 16 1.6129 18 1.31 20 1.005 22 0.853 * 24 0.701 * 26 0.551 28 0.474 30 0.398 For a Uniform Plane Wave of frequency f, determine the Power Density Attenuation for the specified shield thickness.
