Abstract
This thesis is about developing a conformal object using the finite difference time domain (FDTD) method. Theoretical analysis nowadays frequently uses to analyze problem regarding electromagnetic in computational algorithm. The FDTD method by numerically implemented and time based simulation results in better response of wide band frequency. In the FDTD there are several others principles that have been used in modelling the object; they are absorbing boundary condition (ABC), near Field Far Field (NFFF) and Scattering Parameter. This thesis also uses Radar Cross Section (RCS) characteristic to analyze the radiation pattern of the object at particular incident plane wave direction. The source of the plane wave was determined by the angle of phi and theta in the Matlab function. Once the simulation started, GUI immediately shows simulated object. After FDTD iteration completed the radiation pattern on the polar graph plotted in direction of xy-plane, xz-plane and yz-plane. This pattern can be used to analyze the object characteristic, regarding the frequency of the incident plane wave. From the radiation pattern, we can see that conformal (sphere) show less reflection than the cubical object as comparison.
