- Abstract
Current shielding effectiveness (SE) of electromagnetic shielding (EMS) fabric is tested in the plane state, the testing results are difficult to describe the shielding effect of a garment in a curve surface state after manufactured by the fabric. To solve this problem, this study proposes a new SE computation model of the EMS fabric based on a SE vector. The model can calculate a theoretical SE value of the EMS fabric in the curve surface state. A number of factors which determine the SE of the fabric with a curve surface are analyzed according to the principle of the reflection and transmission of the electromagnetic wave. This study also gives a new argument that the curve fabric can be divided into many micro-planes and the fabric SE is considered as a vector. And then a computation model of the SE of the curve fabric is constructed. The detail of computation is deduced, and an application example is given. Results of experiments and analyses show that the method is scientific and correct, and the error between the computation SE value and the testing SE value of the local garment is less than 3%. The model provides a new way to calculate the SE of the EMS fabric with symmetric curved surface.
