摘      要：The use of variational principles with the FDTD scheme is introduced by simulating simple dipole antenna structures. Input impedances of the antennas are computed with the variational method and with direct definition V-in/I-in. The variational method clearly shows a better agreement with the reference results than the commonly used voltage-current ratio-based derivation. (C) 1998 John Wiley & Sons, Inc.
