The shielding of radio wave by steel-containing structures is desirable for electronics protection but undesirable for telecommunication signal reception. This work investigates the shielding behavior of steel structures consisting of members in various configurations, with the practical aim of determining how the configuration can be exploited to control the shielding. Differently oriented continuous steel reinforcement (stranded/unstranded wires in the unidirectional, crossply and planar coil configurations) are evaluated for electromagnetic interference (EMI) shielding at 600–2000 MHz, using unpolarized radiation. The absorption loss SE_A dominates the reflection loss SE_R. The crossply configuration gives the highest SE_A, SE_A/thickness and SE_A/SE_T (SE_T = total loss); the planar coil configuration gives the lowest values. The SE_A, SE_A/thickness and SE_A/SE_T are moderately higher for the crossply configuration than the unidirectional configuration, because steel’s electrical isotropy allows the 0° electric field to interact with the 90° wire. The SE_A/SE_T is comparable for the stranded and unstranded wires.

含钢结构对无线电波的屏蔽对于电子保护而言是可取的，但对于电信信号接收而言则是不可取的。这项工作研究了由各种配置的构件组成的钢结构的屏蔽行为，实际目的是确定如何利用配置来控制屏蔽。使用非极化辐射评估不同取向的连续钢筋（单向、交叉和平面线圈配置中的绞合/非绞合线）在 600–2000 MHz 下的电磁干扰 (EMI) 屏蔽。吸收损耗SE _A支配反射损耗SE _R。crossply 配置提供了最高的SE _A, SE _A /厚度和SE _A / SE _T ( SE _T  = 总损失); 平面线圈配置给出了最低值。的SE_甲，SE_甲/厚度和SE_甲/ SE _Ť是适度高比单向配置交叉帘布结构中，由于钢的电各向同性允许0°电场以与90°线相互作用。该SE_甲/ SE _Ť是为滞留和搓成线相媲美。
