N2 - In the layered medium background, a computation strategy of the quasi-singular terms of the Magnetic Field Integral Equation (MFIE) is proposed, where the normal vector is set in the inner integral. Meanwhile, by this strategy, better accuracy is obtained in the Method of Moments (MoM), when the weak form is discretized by not only the divergence-conforming (RWG) but also the curl-conforming (nxRWG) low-order basis functions. As to the discretization of the RWG basis functions, the symmetric propagation factors in layered medium Green's function (LMGF) ensures that transferring the normal vector into the inner integral is feasible. However, discretized by nxRWG basis functions, the inner product is naturally with the normal vector in the inner integral. A numerical result is presented to show the better behavior gained by this strategy in accuracy.
