(a) Experimental setup for beam steering application. (b) Measured beam offset of the output beam and its radius as a function of the input beam offset. (c) The plate separation and the permittivity profiles of an ideal device, at several different frequencies, along two different cross-sections indicated by dashed lines in Fig. 1b. These are computed using Eq. (3). In these figures, the black solid curves give the desired permittivity profiles along the same two cross-sections.
