携帯電話や無線LAN等の無線通信が壁、窓および人から影響を受けることに注目し、壁面の一部の媒質が異なる方形建造物のモデル内および近傍における電界強度分布を実験値およびFVTD法による計算値の解析を行う。実験モデルとして壁面の全てがコンクリート壁の場合、壁面の一部が窓ガラスの場合、壁面の一部が窓が開放されていることを想定した場合の3つのモデルについての比較を建造物の内側と外側に分けて行った。建造物内では、ガラスからの反射波が強いため壁面の一部が窓ガラスの場合が一番高い電界強度を示した。建造物外側では、壁面の全てがコンクリート壁の場合は、コンクリート内で電波が減衰し、一番低い電界強度を示した。同様に媒質内を透過する壁面の一部が窓ガラスの場合は、コンクリートほどの減衰は見られなかった。 |

A study about electric fields distribution around or inside buildings according to those structures is presented. Radio communications such as mobile phones and wireless LAN systems are affected by walls and windows of buildings when those communication devices are used inside or around buildings. In this paper, electric field distribution analyzed using the building model which was constituted by concrete walls and windows were compared with those analyzed using the building model which was constituted by only concrete walls. In addition, electric field distributions around the building model that some windows were opened partly were analyzed. All measurement data were compared with the numerical results obtained by FVTD simulations. In conclusion, the effect of windows on the electric field distribution was remarkably different from that of concrete walls. Reflection waves from windows were higher than those from concrete walls, and transmission waves through windows were smaller than those through concrete walls. Therefore, electric fields strength around windows became higher than those around concrete walls. |
