  The advent of transformation optics has lead to the initiation of designing
devices and applications associated to electromagnetic wave propagation in
anisotropic media. Here, a method is suggested using a coordinate
transformation with spherical coordinates for the purpose of designing a three
dimensional cloak for a body having an arbitrary convex geometry. For the
purpose of verification of the algorithm, a ray tracing process is carried out
for an ellipsoid having axial symmetry.
