Claim 8:
9. A method for determining an inductance or capacitance value of a variable component within an impedance matching network comprising a plurality of fixed components having fixed inductance and capacitance values and said variable component having a variable inductance or capacitance value, comprising:
a) selecting an initial inductance or capacitance value of the variable component and obtaining a measurement of a voltage indicative of power of a reflected signal received by said impedance matching network;
b) changing the inductance or capacitance value of the variable component in a determined scanning direction and obtaining a further measurement of the voltage indicative of power of the reflected signal;
c) determining a set comprising each inductance or capacitance value of the variable component corresponding to a minimal voltage measurement; and
d) controlling the variable component to set its inductance or capacitance value at a median value of said set;
wherein step b) is repeated until said further measured voltage is strictly greater than a penultimately obtained measurement of the voltage indicative of power of the reflected signal.
