On the electromagnetic reflectivity properties of selected materials

With the high service requirement of mobile communication systems, complex electromagnetic reflectivity properties of common building materials and signals scattering effect in complex indoor environment must be carefully analyzed. This paper put forward a set of detailed studies of a variety of common building materials' reflectivity properties in the process of signal transmission. Measurements involve the shape, size and direction of aluminum, wood, perspex and plasterboard under an anechoic chamber environment. Experiments results proved that the aluminum board and plasterboard show good reflection ability while wood material proves to be less satisfied reflector. Absorber put behind Perspex board is demonstrated able to make a big difference on Perspex board's reflection performance.
