Line-Surface Formulation of the Electromagnetic-Power-based Characteristic Mode Theory for Metal-Material Combined Objects — Part II

Authors: Renzun Lian

In the Part I of Line-Surface formulation of the ElectroMagnetic-Power-based Characteristic Mode Theory for Metal-Material combined objects (LS-MM-EMP-CMT), the relevant fundamental principle had been established, and some very valuable complements and improvements are done in this Part II. In this Part II, the traditional surface equivalent principle for a homogeneous material body whose boundary is only constructed by a closed surface is generalized to the line-surface equivalent principle of a homogeneous material body whose boundary can include some lines and open surfaces besides a closed surface; a new line-surface formulation of the input/output power operator for metal-material combined objects is given, and the new formulation is more advantageous than the formulation given in Part I; some more detailed formulations for establishing LS-MM-EMP-CMT are explicitly provided here, such as the formulations corresponding to the decompositions for currents and their domains and the formulations corresponding to variable unification. In addition, a new concept intrinsic resonance is introduced in this paper, and then a new Characteristic Mode (CM) set, intrinsic resonant CM set, is introduced into the EMP-CMT family.
