چکیده :

The calculation of the Jacobian matrix is crucial in inverse scattering problems. A more accurate Jacobian leads to greater stability and faster convergence in these inverse problems. Thus, the choice of the forward solver is vital for both calculating the Jacobian matrix and addressing the subsequent inverse problem. In this study, we evaluate the capabilities of numerical Jacobian calculation using the approximate semi-explicit Method of Moments (MoM) in comparison to two common methods. Our results indicate that the accuracy of the Jacobian calculated using the approximate semi-explicit formulation is comparable to that of other methods, while also being more computationally efficient.
