Query: Analytical Representation of Characteristic Modes Decomposition   Aspects of the theory of characteristic modes, based on their variational
formulation, are presented and an explicit form of a related functional,
involving only currents in a spatial domain, is derived. The new formulation
leads to deeper insight into the modal behavior of radiating structures as
demonstrated by a detailed analysis of three canonical structures: a dipole, an
array of two dipoles and a loop, cylinder and a sphere. It is demonstrated that
knowledge of the analytical functional can be utilized to solve important
problems related to the theory of characteristic modes decomposition such as
the resonance of inductive modes or the benchmarking of method of moments code.
