Hi all,

In the paper "

In the figure, the non-Euclidean space (the surface of a sphere) touches the Euclidean space (the plane) like a piece of paper partially wrapped by a globe. The plane carries bipolar coordinate grid and the surface of the sphere carry a grid too. The line where the sphere and the plane touch is a quarter circle or meridian.

So, my question is that: how can I draw the graph using Wolfram Mathematica or Maple?

Best wishes,

In the paper "

*Broadband Ground-Plane Cloak*" (http://www.sciencemag.org/cgi/content/abstract/323/5912/366), the author gave us a novel scheme to design non-Euclidean cloak. And the electromagnetic space is shown as bellow.In the figure, the non-Euclidean space (the surface of a sphere) touches the Euclidean space (the plane) like a piece of paper partially wrapped by a globe. The plane carries bipolar coordinate grid and the surface of the sphere carry a grid too. The line where the sphere and the plane touch is a quarter circle or meridian.
