Funny you asked ..... here's my current spice model : http://lenr.qumbu.com/web_hotcat_spice/130625_spice_18.png Here's the Levi curve : http://lenr.qumbu.com/web_hotcat_pics/130601_levi_12A.png Here's the Ericsson curve : http://lenr.qumbu.com/web_hotcat_spice/130628_ericson_02.png Here's my simulation with HEATER power only, applied to the OUTSIDE (top) and INSIDE (bottom) http://lenr.qumbu.com/web_hotcat_spice/130625_spice_20.png Their model isn't calibrated -- mine is. Allowing for the different voltages, the SHAPE of the Ericson curve clearly shows that the "sine-like" wave only occurs if excess pulsed power comes from the INSIDE, not the OUTSIDE.
