Voltage Controlled Intertwined Spiral Arrays for Reconfigurable Metasurfaces

Figure 6

Transmittance and reflectance of the AFSS with the unit cell of Figure 1 at normal incidence of a y-polarized wave when the four pin diode switches in the spiral arms are in the on (solid lines) and off (dashed lines) states. The on and off states of pin diodes are modelled with their equivalent circuits of Figure 4.
