Abstract:

This paper adop ts a typ icalmeshlessmethod, that is, the element2free Galerkin ( EFG) method, to solve the electromagnetic p roblems in frequence domain. The EFG discrete form for the multi2medium electro-magnetic wave equation in frequence domain is first deduced by purely using the weighted residual method. Then, aiming at a classic electromagnetic p roblem where the TE p lane wave is reflected by a metal-backed die-lectric slab, numerical computation is carried out. The results obtained by the EFGmethod are finally compared with those obtained by the finite elementmethod ( FEM) , concluding that the former is of greater accuracy.

Key words: meshlessmethod, element-free Galerkinmethod, frequence domain, electromagnetic field, reflection coefficient
