[其它]PEEC Modeling and Reduction Studies Based on Nonuniform Mesh and Arnoldi Algorithm

Abstract—With the increase of the conductor dimensions and the ]q<Zc>OC  
considered frequencies, the effective mesh and model reduction fFNwmH-jv  
approaches must be studied. Based on the current distribution eZk4$y  
regularity of a conductor, this paper puts forward a novel multi-skin %VmHw~xyF:  
depth non-uniform mesh method (MSDNMM). Then, the intrinsic s6.#uT7h  
numerical ill-conditioning of Asymptotic Waveform Evaluation I'>r  
(AWE) reduction method is pointed out due to the direct moment {v~.zRW%]r  
matching. Furthermore, Arnoldi algorithm is proposed to reduce the C3z#A3&J  
high-order original system. The new algorithm transfers the moment K6nGC
