    A new higher-order method of moment (MoM) technique is presented for volume-surface integral equations (VSIE)for electromagnetic modeling of composite metallic and dielectric objects. The higher-order MoM scheme comprises higher-order hierarchical Legendre basis functions and an accurate representation of the object by higher-order curvilinear elements. Due to the orthogonal nature of the basis functions the continuity condition at the interface between metal and dielectric is satisfied explicitly. By utilizing the continuity condition the number of unknowns can be significantly reduced, especially for metal objects with thin dielectric coating.
