The impact of frequency selective surfaces applied to standard wall construction materials

A bandstop frequency selective surface (FSS) is attached onto existing common construction materials to transform the standard material into a frequency selective filtering wall. The modified building material shows an additional 30 dB attenuation at the resonant frequency, which is a sufficient attenuation to isolate an indoor wireless system from undesired external interference. Measurement results in the X-band (8.2 GHz - 12.4 GHz) show that the frequency selectivity is closely related to the illumination angles and the electromagnetic properties of each material.
