(a) Imaginary part of the complex potential V(x,y) discussed in the text. Red and blue regions correspond to gain and loss, respectively. (b) Iso-contour of the beam intensity launched onto the potential in a through a circular aperture of radius ∼40λ0, where λ0 is the free space wavelength. Also shown are three transverse intensity plots (from bottom to top) at z=0, z=5, z=10. (c) Transverse power flow pattern (indicated by arrows) of the beam at z=5.
