現実の建造物を想定した、複数近接している集合住宅間の外壁媒質が異なることによる周辺の電界強度分布の変化について解析を行う。実在する6棟近接している建造物をモデルとし、建造物外壁がコンクリートの場合、外壁が金属系の場合及び建造物間のみの外壁が金属系の場合を想定し、コンクリート縮小モデルを用いた外部入射波における建造物周辺の電波伝搬実験を行う。また、FVTD法を用いた数値解析を行い両者の比較を行う。建造物間のみの外壁が金属系の場合は、外壁がコンクリートの場合に比べ建造物後方で電界強度が強くなる。また、外壁が全て金属系の場合に比べ、建造物後方の電界強度は同程度であるが、反射、散乱が減少することにより建造物前方及び側方の電界強度が弱くなることが確認できた。 |

Electric field distribution in neighborhood of a forest of apartments was measured to be understood that they will change according to materials of walls. The real forest apartments were modeled for this study and reflection waves were measured as transmitting incident waves from outside of the model. The forest apartments were constituted by six apartments and each apartment was made by concrete walls. In this paper, electric field distributions around the apartments were compared by changing the location of conductive covers outside of the concrete walls. According to these comparisons, putting conductive covers on the outside walls which are close to a next apartment is effective way to lead electromagnetic waves toward the back of the apartments. Comparisons of electric field distributions around the apartments covered by conductor plates only on the walls being close to a next apartment and those around the apartments fully covered by conductor plates showed that backwards distributions were almost same, however, scattering waves to front, left and right sides became higher in the case being covered fully. Measurement data were compared with numerical data obtained by FVTD analyses and they agreed very well. |
