We propose a more practical method of realizing the superfocusing modes based on waveguide structures, and present a numerical analysis of these structures using finite-difference time-domain (FDTD) simulations. For metallic wedged structures coupled to dielectric waveguides, we investigate a method of controlling superfocusing by changing the phase of waveguide modes.
