Three-dimensional unstructured tetrahedral and hexahedral "nite element mesh optimization is studied from a theoretical perspective and by computer experiments to determine what objective functions are most e!ective in attaining valid, high-quality meshes. The approach uses matrices and matrix norms
means of three numerical examples, the functional showed better agreement with the reference results than the traditional scheme, in which the feeding point impedance is computed directly from the ratio of the feeding point voltage and current. Variational-based methods offer a new and more accurate
