Geometrical optimization of sensors for eddy currents. Non destructive testing and evaluation

Using genetic algorithms for compensating the local magnetic perturbation of a ship in the earth's magnetic field

“…The GA is based on an initial population, which is created randomly. The evolution of the generations is controlled by three fundamental operators, namely, selection, cross, and mutation [2,6,8,10,12]. The operator "selection" chooses the parents for the next generation according to their fitness.…”

“…For the reliable use of these radar services, the development of UWB antennas operating from 3.1 to 10.6 GHz is inevitable. To satisfy such a requirement, various wideband antennas have been studied [2][3][4]. Among the many possible alternatives, printed monopole antennas have been extensively investigated because of their attractive features such as light weight, simple structure, and ease of mass production.…”

“…In general, the procedure for minimizing the magnetic anomalies created by ships is based on experiments [1][2][3][4], especially due to external factors that influence the process [5][6][7]. In any case, these experiments rely on the availability of a fast-optimization algorithm, which must calculate the values of the currents and number of turns needed to produce a magnetic field, which is able to compensate the magnetic field created by the ship.…”

An NDT Pulse Shape Study With TEAM Problem 27

“…Other work also included the design of a genetic optimization algorithm to design a well adapted sensor [3]. More recently, an algebraic multigrid approach to this problem was presented [4].…”

Finite Element Method Applied in Electromagnetic NDTE: A Review

“…Design and validation of a new sensor configuration is one of leading topics in EC NDT and is often supported with FEA [72][73][74]. Aming at an optimized sensor configuration, Robaina et al [75] developed a 3-coil set-up with two excitation coils and a middle acquisition coil, serving to determine material properties by means of an eddy-currentrelated change of a magnetic flux.…”
