In this study, an efficient meshless method named mixed radial point interpolation meshless method supplemented by a new (mixed) basis function is proposed. The proposed basis function is the multiplication of two conventional basis functions and possesses some extraordinary properties in comparison with conventional ones. In order to investigate the improvements of this basis function, an important type of electromagnetic problems, i.e. parallel plate waveguide with an internal discontinuity is analyzed. It is seen that the mixed basis function possesses better precision and convergence rate with respect to other basis functions.
