After comparing the NEC software’s results with other references’, the software’s validity in calculating the shielding effectiveness (SE) of complex metallic wire structure is verified. So the SE for an incident electromagnetic wave of the structure built with reinforcing wire mesh can be discussed at the base of the results computed by NEC. Several modes built with reinforcing wire mesh were computed by NEC in the paper and the results show that reinforcing wire mesh has good SE for electromagnetic wave while its SE is determined by many factors such as the frequency of the incident wave, wire grid size, wire radius etc. Some conclusions are useful for the EMP shielding, relay-cell design in substation and so on. |
