“…The frequencies and Q factors of the first three SR modes are given. Our FDTD results with ''knee'' model are close to the data reported by Pechony and Price [2004], and somewhat lower than values calculated by Morente et al [2003]. A large difference is found with the frequencies predicted by Nickolaenko et al [2003], which are approximately 2 times higher than our FDTD results.…”

“…modes is found between the results calculated by transmission line matrix method (TLM) [Morente et al, 2003] and our FDTD model. It is believed that this difference comes from the different way to terminate the upper boundary of the cavity in these two models.…”

“…It is believed that this difference comes from the different way to terminate the upper boundary of the cavity in these two models. Morente et al [2003] locate the upper boundary of the Titan resonant cavity at about 180 km, where the conduction current is about one order of magnitude greater than the displacement current. At this altitude, the conductivity is approximately 10 À7 S/m.…”

“…[16] The conductivity profile (Figure 1) used in our FDTD model is taken from Pechony and Price [2004], which is very close to the profile used by Morente et al [2003]. However, a 2 -7 Hz difference in the first three Figure 4.…”

Three‐dimensional finite difference time domain modeling of the Schumann resonance parameters on Titan, Venus, and Mars

[1] The conducting ionosphere and conducting surface of Titan, Venus, and Mars form a concentric resonator, which would support the possibility of the existence of global electromagnetic resonances. On Earth, such resonances are commonly referred to as Schumann resonances and are excited by lightning discharges. The detection of such resonances on other planets would give a support for the existence of the electrical discharges in the lower atmosphere on these planets. In this paper, a three-dimensional finite difference time domain modeling for the extremely low frequency propagation is employed to study the Schumann resonance problems on Titan, Venus, and Mars. The atmospheric conductivity profiles for these studies are derived from the previously reported ionospheric models for these planets. The Schumann resonance frequencies and Q factors on these planets are calculated and are critically compared with those obtained from the previously published models.
