Use of the Techniques for Uniaxial Medium in General Curvilinear Coordinates

In this work, it was introduced some considerations about the formulation of the method to uniaxial medium and its implementation in the electromagnetic scattering and of problems in 2-D and 3-D. The methodology used was the technique LN-FDTD, developed to reduce the instability of the method. So that the characteristics of the electromagnetic structures of complex geometry (head), it can be explored.
