Abstract :
New finite-difference time-domain (FDTD) update equations for long thin wire are presented. The axis of long thin wire is assumed to be diagonal to the Yee cell faces. Derived using the contour-path method, the new equations properly models the singular field near the long thin wire. A dramatic improvement in computed accuracy was observed when a stripline with long thin wire diagonal to the Yee cell faces in FDTD grid was analyzed using the new FDTD equations.
