Abstract :
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.
