RESOLUTION OF MAXWELL’S EQUATIONS IN A NON STAGGERED GRID MODEL

Abstract — In this paper a scheme to obtain an adaptive method in space for the resolution of Maxwell’s equations is presented. Using interpolating wavelets it is possible to obtain an adaptive grid allowing an economy of the computational resources. Using the non staggered grid model the stability factor is improved when compared with the classic FDTD and its value is greater that one. This factor is more limited with the increase of the interpolating polynomial. On the other hand the dispersion proprieties are more restricted, when compared with a staggered grid model
