摘要：

A new accurate interpolation methodology is proposed for frequency sweeps arising in the partial element equivalent circuit (PEEC) method. Since the PEEC method models separately the magnetic and the electric field contributions to the mixed potential integral equation, they fluctuate slowly with frequency and, thus, can be interpolated more easily than the global entries of the final matrix, either in the case of nodal or loop or modified nodal analysis. Numerical results confirm that the proposed method yields more accurate matrices over the frequency band than direct interpolation.
