A method based on the method of lines which discretizes a partial differential equation (PDE) into a system of ordinary differential equations (ODEs) is presented. A difference scheme with an error of O(h4) is introduced and a simple method for determining the general solutions of the ODEs is given. Finally, the least-square approximation is used for improving the accuracy of the numerical results. Some numerical results for rectangular coaxial line, ridge waveguide, and shielded stripline are also given. These results are in good agreement with that published in literatures.
