Common-mode radiation characteristic analysis of connections between cables and metal cases

Abstract

In this paper, the common-mode radiation characteristic of the connection between a cable and a conductor is analyzed by the electric field integral function (EFIF) and the method of moment (MoM). The RWG basis function is adopted as the conductor basis function, the pulse basis function as the wire basis function and the juncture employs Costa basis function. A scheme of singular region separation is proposed to overcome the integration singularity of juncture matrix elements. Some new conclusions of the common-mode radiation characteristics with the metal case are obtained by numeration.
