Notes:
The input reactance of a pair of coupled coils is a function of the latter's primary, secondary, and mutual inductances as well as the secondary tuned frequency. It is thus possible to synthesize two appropriate equivalent inductances for use in a double-tuned probe by a judicious choice of these parameters. From a given coil configuration and hence the associated self and mutual inductances, the present note analyzes and derives the essential equations showing the possible values of the tuned secondary frequency to be used to design this type of probe circuit first proposed by Fitzsimmons, Brooker, and Beck [Magn. Resoh. Med. 10, 302 (1989)]. In cases where an intercoil coupling capacitor is needed, its value also can be calculated from a biquadratic equation. A numerical example is given to check the validity of the theoretical results.
