Abstract

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