Field-induced electromagnetic shielding material show an abrupt decrease of resistance when external electromagnetic field exceeds a threshold value, the material will occur metal-insulator transition phenomena in the nanosecond time, Owing to threshold value was so high that traditional static test method and low-voltage dynamic test can not satisfy test require. According impedance matching principle...
A scheme is proposed for predicting the electromagnetic shielding properties of multilayered composites containing multiple inclusions of diverse shapes, volume concentrations, and spatial distributions based on homogeneous comparison materials and the plane-wave shielding theory. This scheme leads to completely explicit formulas for the shielding effectiveness and reflected loss of multilayered composites...
The test method of shielding effectiveness (SE) based on traditional definition was given and its shortages were analyzed. The measurement of SE using reverberation chamber based on statistical property was propounded. The simulation results indicated that sampling at the middle line can reflect the shielding property of enclosures effectively. A new testing system based on the statistic definition...
