Abstract [en]

Utilizing the Partial Element Equivalent Circuit (PEEC) method to simulate electromagnetic structures attached to linear and nonlinear circuits has been proved to be a promising approach for this type of problems. The PEEC method offers an equivalent circuit for any electromagnetic structure which in turn can be connected to any linear or nonlinear circuit. A blocked structure exists in the resulted system matrix. This pattern offers an opportunity to devise customized factorization methods to solve the system of equations in a faster and optimal way. In this paper, a novel factorization technique has been proposed which reduces the computational cost to a great extent. Instead of calculating the LU factorization of the whole system at eachiteration, the LU factorization has been obtained by updating the LU factorization at the previous iteration with much fewer numerical operations. A great speed up in the simulation has been achieved.
