This approach really develops an effective method for impedance matching design and reduced the time for trial and error. Moreover this method makes the implementation procedure less complex. Keywords: Wide-band transducer‚ impedance matching‚ tuning‚ equivalent circuit 1. Introduction Piezoelectric transducers are used for under water applications. As we know higher frequencies are more easily attenuated in water‚ so low frequency sound waves are used for under water mapping
