Abstract :
The Method of Moments matrix equation, resulting from the electromagnetic simulation of a high frequency planar circuit can take much memory and time to solve, typically O(n/sup 2/) resp. O(n/sup 3/). This paper proposes a new solution strategy combining a Multilevel Moments Method scheme with a Modified Diakoptics technique and a Block Gauss-Seidel iterative technique, effectively reducing the solution time.
