(Color online) (a) Computational domain on the active radome; [(b), (c) and (d)] the near electric fields corresponding to the three cases at , the electric fields are recorded when the simulation reaches steady state.

Image of FIG. 4.
FIG. 4.

Simulated radiation patterns at for three cases: (a) the S rings in each region are loaded with the same capacitors (case I), (b) the capacitive values in each region are listed in Table I (case II), and (c) the capacitive values in each region are list in Table I (case III).

Image of FIG. 5.
FIG. 5.

Theoretical result of the radiation patterns at for three cases: (a) no phase difference along the aperture, (b) the phase is linearly changed from 0 to along the aperture, and (c) the phase is linearly changed from 0 to along the aperture.

Tables
