Abstract:
A method for calculating an optimum transducer power gain for an impedance matching network comprising the following steps:(a) inputting reflectance values qin and corresponding frequency values fin over a selected frequency range; (b) initializing an optimum transducer power gain value G; (c) computing a center function k from G, fin and qin; (d) computing a radius function R22 from G, fin and qin; (e) resampling k and R22 over a defined frequency grid; (f) extrapolating k and R22 to smooth end points at infinity; (g) extending k and R22 to conjugate matched negative frequencies; (h) determining whether a reflectance function lies within a performance disk defined by k and R22; (i) decrementing G and continuing from step (c) if no reflectance function lies within the performance disk; (j) and outputting G as the optimum transducer power gain value if a reflectance function lies within the performance disk.
