Design of a New Bi-State Active Frequency Selective Surface
This paper presents a bi-state frequency selective surface (FSS) designed using a passive and active FSS on both side of a thin dielectric substrate. Specifically, the proposed unit cell (of the bi-state FSS) includes a passive loaded cross dipole FSS on one side and an active dipole (utilizing PIN diodes) with perpendicular bias lines on the opposite side. The proposed bistate FSS is capable of functioning in reflection mode when the active FSS is reverse biased, and in transmission mode when forward biased. The proposed design also features reduced electrical size, thereby reducing the sensitivity of this design to incident angle of the interrogating electric field.
