Abstract (in Japanese) (See Japanese page) 
(in English) In this study, we focus on practicality of the wave absorption film with
sheet resistivity of 188.4Ω□. Several characteristics in case of arranging this film on the surface of wall material and arranged effect by using indoor analysis model are examined analytically and experimentally. As a result, there are good agreement with theoretical values and measured values of reflection and transmission characteristics. Frequency dependent of these characteristics are not also confirmed. Furthermore, grazing incident characteristics from the upper side of the film are examined theoretically, and incident angle dependent of them are clarified. Moreover, arranged effect is analyzed by FDTD method.As a result, it is confirmed quantitatively that electric field intensity of indoor space becomes stable. Effect of Suppression to reflected wave from wall is also clarified analytically by focusing electric field intensity from antenna to wall.
