This paper presents a graphics processing based im- plementation of the Finite-Difierence Frequency-Domain (FDFD) method, which uses a central flnite difierencing scheme for solving Maxwell's equations for electromagnetics. The radar cross section for difierent structures in 2D and 3D has been calculated using the FDFD method. The FDFD code has been implemented for the CPU calcu- lations and the same code is implemented for the GPU calculations using the Brook+ developed by AMD. The solution obtained by using the GPU based-code showed more than 40 times speed over the CPU code.
