Abstract


In this research , we used the fundamentals of the finite difference time domain (FDTD)  meth od  to solve Maxwell's  equations in the time domain . The Finite Difference Time Domain has become the most widely used for modeling and simulation tools of  Electromagnetic phenomena ; this  method depends on the replacement of derivatives by finite difference and it has been applied to many problems of propagation , radiation and scattering  of Electromagnetic waves .The FDTD method employs  a second order finite central approximation to the space and time derivatives in Maxwell’s  curl equations , and giving rise to a new discrete Electromagnetism with a particular space position. These solutions and analysis of  Electromagnetic waves (Microwaves) where done by using FDTD definition for an orthogonal cubic unit spatial grid whose depending on Yee unit cell.
