Hello,
My simulation schematic is a voltage source stimulating an inductor L0, coupled to another 2 inductors (L1 and L2, through k1, k2). each of them is connected in series with a 50 Ohm resistors. The voltage source is 64.3V-amplitude 2MHz sine wave.
The simulation result of V_L0, V_L1, V_L2 are shown in the second graph, representing transient voltage drop across L0, L1, L2, respectively.
Does any one know what is the cause of this oscillation?
Thanks in advance.

The mutual inductances are used to model the EMI coupling in EMC BCI test.
