This paper investigates influence of the regularization parameter L on the performance of subspace-based optimization method in reconstructing uniaxial anisotropic objects. Some criteria are obtained to determine the regularization parameter L. If L is too small, the cost function may not converge well. If L is too large, the noise will be amplified and deteriorate the inverse process. It is found...
Due to the nonlinear property of large uniaxial anisotropic scatterers, many iterative optimization methods have a high risk of being trapped in local minima. In this paper, a frequency-hopping subspace-based optimization method (SOM) is proposed to reconstruct the relative permittivity distribution of 2-D large uniaxial anisotropic scatterers with transverse electrical (TE) illumination. This hybrid...
