Abstract :
With the widespread application of electronic products, the hazards of electromagnetic radiation has been drawn much attention. Thus, electromagnetic shielding materials are widely used to suppress electromagnetic radiation. In this paper, test methods of shielding effectiveness of materials ware reviewed. A microstrip-based test system for shielding effectiveness measurement was proposed. Measurement results of S21 parameter for two special shielding materials in the 10 MHz-3 GHz ware derived by this test system. It is shown that this test system can be used to estimate shielding effectiveness (SE) of some plane materials.
