EM SHIELDING OF BUILDING MATERIALS

Abstract

This report covers the results of a program for measuring the shielding effectiveness (SE) of building materials. Part 1 of the report describes a number of techniques which were used to make radiated measurements of magnetic field SE from 10 Hz to 50 KHz and conductive measurements from 10 Hz to 1 GHz. A method was introduced for plotting the low frequency field distribution about various shaped ferromagnetic enclosures. Part 11 contains a group of the significant results of the radiated measurements on a variety of building materials. A collection of tables shows the measured electrical parameters and the calculated shielding obtainable from a cross-section of dielectric building materials.
