Wide use of electrical and electronic devices in everyday life give rise to a dispute about the harmfulness of electromagnetic radiation on human body. Electromagnetic radiation also causes malfunctions of devices and interference of the signals transferred from one instrument to another. Therefore, electromagnetic shielding becomes a more important topic as more electronic devices and house hold apparatuses are supplied and used for enhancing the convenience of human life. This study attempts to show the experimental results on the electromagnetic shielding effectiveness of woven fabrics made of stainless steel fibers. We designed and constructed a measuring system, consisting of a network analyzer and a device that plays the serves as a sample holder and at the same time as a transmission medium of the incident electromagnetic wave. Experimental results show that the metal fabrics have a very good electromagnetic shielding effectiveness. The shielding effectiveness results from the reflection loss rather than the absorption loss, even though the material itself has a good absorption property. Thus, the shielding mechanism of metal woven fabrics is more influenced by structural parameters than by the electronic properties of the fiber material
