Design method of arbitrary three-dimensional non-conformal ellipsoid invisible cloak

The invention relates to a design method of an arbitrary three-dimensional non-conformal ellipsoid invisible cloak. In theory, by establishing a three-dimensional non-conformal ellipsoid cloak model,a Jacobian matrix for measuring a transformation relation between two coordinate systems is obtained by virtue of a coordinate transformation theory, and then a cloak material parameter formula basedon tensor analysis is elicited; in a simulation process, Comsol Multiphysics software based on finite element analysis is utilized for carrying out full wave simulation, a three-dimensional distribution diagram of a z-direction amplitude of an electric field is obtained by selecting ellipsoid cloaks with different parameters and setting different conditions, the invisibility of the designed cloakis realized by virtue of a result of the diagram, and the correctness of a material parameter expression formula disclosed in the theory is verified based on the tensor analysis; and detailed method flow is described in the fig
