Using this meth d, the c nvergence speed f wire kernel and its relative integrals expressed as exact series representati ns is greatly accelerated, and hence the c mputing time f r the impedance matrix Z is greatly reduced. Finally, the validity and usefulness f the new meth d are illustrated with its applicati n t m derately thick cylindrical wire antennas.
