Abstract :
An improved algorithm for the method of lines (MoL) is presented. It converges much faster than the conventional method. While the error in the MoL is typically O(H/sup 2/), the error in the modified MoL is reduced to O(H/sup 4/). Therefore, accuracy can be maintained with a much smaller number of lines, leading to reduced matrix sizes and thus accelerating the algorithm considerably. Numerical results obtained for a microstrip line illustrate the advantages of the approach.<>
