Effects of LIGHTNING RETURN STROKE: Voltages, currents and powers at various altitudes involved in an earth to cloud (3000m altitude) return stoke. The ionized return path is modeled by means of non linear TL cells. Sim time less than 1 sec, with 100K points per waveform (I7 processor,12.5% CPU core load).

Effects of pcb versions on the startup of the overtone crystal oscillator. The "short" TLs that model the pcb traces (5ps/mm) have a major impact on this behavior.

Spectrum of the signal related to the overtone crystal oscillator. The peak frequency (about 178.6 Mhz) corresponds to the fifth harmonic of the quartz connected to the feedback loop of the ECL amplifier. As known this kind of sims involving high-Q components , switches and "short" TLs are practically impossible with Spice.
