摘要：

A new hybrid technique is presented, which combines the method of moments with the finite difference time domain (FDTD) method to analyse electrically short, thin-wire antennas located in the vicinity of inhomogeneous dielectric bodies. The antennas are dealt with in the frequency domain using the NEC code, while the FDTD method is used to analyse the inhomogeneous part of the; problem. The two sub-problems are combined by invoking the equivalence theorem.
