A newly developed computation method,the multi-grid method(MGM),is discussed. The voltage distributions and impedances in a shelled microstrip line has been computed with the method to show the advantage over the fixed grid iteration method.The FMG (full multi-grid)method is applied in computing the even and odd module voltage distribu- tions and impedance of shalled VIP(vertically installed planar)structure coupled micropstrip line.The results show that the MG method is a high-speed,good-accuracy computation method in electromagnetic numerical analysis.
