MIXED METHOD FINITE-DIFFERENCES, INTEGRAL -EQUATIONS APPLIED TO THE THEORETICAL SIMULATION OF EXPERIMENTATIONS

In order to simulate theoretically experimentations, a novel time doma in method based on the coupling between the finite difference (FDTD) a nd the integral equation has been developed, This mixed method takes t he advantages of each one : FDTD for modelling surface or volume and i ntegral equation for thin wires representation. Typically, this code t hat has been developed can be applied for the study of the coupling be tween a wire grid antenna (log periodic, Yagi .... ) and a metallic or dielectric structure. A presentation of each component of the method is made, then the principle of the mixed method is described. Finally, the application on an example validates the code.
