Shielding Effectiveness Evaluation Using a Non-Standardized Method

Abstract

This paper presents a shielding effectiveness evaluation for some metallic threads materials. The tests were performed using a non-standardized method in a dual transversal electromagnetic cell (DTEM). The materials’ shielding characteristics must be properly evaluated in order to choose an appropriate shielding material. The tests were conducted for three different types of material designated for electromagnetic shielding. The tests were conducted with a non-standardized method which uses a simple and economical setup, with only two components: a DTEM cell and an EMI Test Receiver. In comparison with the standardized methods, the non-standardized method one used does not require large testing space and complicated setup and the material probe needed for DTEM measurements is considerably smaller than the one necessary for the standardized tests.
