抄録

In city area, electromagnetic interference caused by buildings is a very important problem. For example, a well known ghost phenomenon is caused by interaction between incident and reflected waves caused due to the presence of large and tall buildings. The characteristics of the radio waves absorption have been measured by coaxial-wave-guide unit or curtain wall specimens. But these measurements have some demerits. In this paper, a new measurement technique by panel specimen using parallel wire line is proposed and the accuracy of the this technique is verified. An examination of return loss by the fertile concrete panel specimen is carried out. It was shown that the measurement accuracy using parallel wire line and coaxial-wave-guide are almost equal. However, the parallel wire line technique can measure the characteristics of the radio wave absorption without being effected by the electrical environment around.
