Abstract :
In this paper, we propose an algorithm that could be utilized to design an optimal eddy-current sensor. The optimal sensor should provide high sensitivity, especially to deep located flaws and good spatial resolution. Such aims could be achieved only by simultaneous optimization of sensor construction and operating frequency.
