In this paper, we present a multifunctional active frequency selective surface (MAFSS), which consists of two metallic layers and a substrate layer. Three electromagnetic functions of switching, polarization selection and frequency tuning, are integrated into a single board. The bias networks are embedded in each layer and comprise the MAFSS elements themselves, which eliminates the need of extra...
This paper proposes a 2-b multifunctional active frequency selective surface (MAFSS) whose structure is made up of two metallic layers printed on both sides of an F4BME substrate, measuring $320 \times 320 \times 0.8$ mm3. The PIN diodes, embedded on two metallic layers, are controlled through two independent sets of external dc bias network. No additional feeder lines are considered necessary within...
