An approximately correct relation is that the primary circuit must 
resonate at the same frequency of the secondary+tertiary system.
there is no important relation between the resonances of the 
secondary and the tertiary.
The relation, considering Inductances L1, L2, and L3 and
capacitances C1 and C3 (ignoring the capacitance of the secondary)
is: L1*C1=(L2+L3)*C3.
But, as L2 has self-capacitance, this relation is never exact. C2 can
be correctly taken into account with some additional complications,
as I describe in:
