Depth-selective bridging transmission scheme (CST simulations) (a, b). By varying the input phases φ of a 20-antenna array, radiated energy can be focused not only at different angles (as in beam steering) but also at different depths. As an example, two receiving antennas are placed at (a) (x=0, y=10) μm and (b) (x=0, y=25) μm. Depending on the employed phase profile, the radiated power is sent to the front or rear antenna, see left column. The E-field distribution (λ=1550 nm) and the associated phase profile for both configurations is shown in the right column.
