Modeling a Low-Cost Frequency Selective Wall for Wireless-Friendly Indoor Environments

A simple, low-cost frequency selective (FS) wall which filters out a particular frequency with about 30 dB attenuation is constructed by covering an existing wall with a custom designed Frequency Selective Surface (FSS). With 10 mm air spacing between the FSS cover and the wall surface, independence between the two can be achieved. Under such a scenario, performance of the FS wall can be evaluated by cascading the FSS and the wall responses individually. Good agreement between the cascaded evaluation and the actual measured transmission response was found
