Reconfigurable
This paper presents a low-profile, dual-stopband active frequency selective surface (AFSS) with an ultra-wide band ratio (BR) to overcome the limited tuning range and suboptimal profile of current designs. The proposed design consists of a periodic pattern printed on the top of a thin substrate and a bias network on the bottom, with varactor diodes symmetrically mounted on the top metal layer. Based on the equivalent circuit model, the mechanism of wideband tuning is analyzed theoretically.

In the first four txt files, the first two numbers in the file name represent the phase change interval, while the third number represents the phase change step. For example, the first dataset shows that the phase ranges from 0 to 60° with a step size of 15°. In the fifth txt file, the Q value fluctuates between 2 and 4° with a phase step of 1°.
