As a directively method of Maxwell equations, which was first put forward by Yee, FKTD Method has received of the internal and external research workers considerable attention. Recently, the popularity in wave-field calculating of this methok seems from its own advantages. 1.It is not limited to a specific geometry, 2.It don not restrict the constitutive parameters of a scatter. 3.It provides a direct solution to problems with transient illumination. In this paper. We tried to give the FDTD formulation of Maxwell equations in circular cylindrical coordinates. Through the calculating experiment, verified the steady and pricision of this method.
