Abstract

BEM analysis of transient electromagnetic fields based on vector potentials H. Kawaguchi & T. Honma Department of Electrical Engineering, Faculty of Engineering, Hokkaido University, Kita 13, Nishi 8, Kita-ku, Sapporo 060, Japan ABSTRACT Authors have discussed BEM analysis of transient electro- magnetic fields which are produced by relativistic charged particles. The velocity of the particle, however, was 90 percents of the light velocity, j5( = i>/c) = 0.9, at most, because of numerical difficulties of relativistic electromagnetic fields. This paper discusses these difficulties using wake fields in an accelerator cavity as an example of transient electromagnetic fields. INTRODUCTION Authors have discussed BEM analysis of transient electro- magnetic fields which are produced by relativistic charged particles [1], The velocity of the particle, however, was 90 percents of the light velocity, j3(-u/c) = 0.9, at most, because of numerical difficulties of relativistic electromagn
