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

Abstract—With the increase of the conductor dimensions and the ,W*<e-  
considered frequencies, the effective mesh and model reduction ?$-OdABXHK  
approaches must be studied. Based on the current distribution u4z]6?,"e  
regularity of a conductor, this paper puts forward a novel multi-skin HOykmx6$  
depth non-uniform mesh method (MSDNMM). Then, the intrinsic 2c8,H29
