✦ Synopsis

Two different types of source excitation for finite-difference ( ) time-domain FDTD simulations, i.e., electric and magnetic field types, are in¨estigated in this work for configurations that ha¨e no ground planes. This paper shows that the electric field excitation introduces errors in the computed admittance of the de¨ice due to the frequency dependence of the gap admittance, while the magnetic field excitation does not suffer from this drawback; consequently, the latter is better suited for circuit simulations.
