“…Worldwidelly, current BQP (Bi-quadratic polynomials) approach is used to solve the globally convergent algorithm of coefficient inverse problems in the spatial dimension of two. Since it had been proposed in [1,2], recognized and named as BQP approach in article [3], fortunately, it already had been adopted in numerous publications such as [4], [5], [6,7,8,9], and so forth. Actually, the methodology is worked to recover the profile of realistic systems (parabolic, hyperbolic, elliptic type) in industrial, electricmagnetic, optical frequency sounding, engineer, medical tomography, physical as well as chemical fields.…”
