A New Technique for the Analysis of Energy Coupling and Exchange in General Antenna Systems
This paper provides a deeper insight into the character of electromagnetic interactions by learning sensible settings of sturdy and weak mutual coupling involving typical antenna parts coupled through the near field. We tend to develop new techniques capable of analyzing the dynamic structure of generic antenna–antenna interactions by describing how energy exchange is divided between propagating and nonpropagating elements in an exceedingly manner reflecting the geometrical shapes and interelement distances of the coupled antennas. The proposed method is implemented through a special methodology-of-moment (MoM) numerical model and is employed to offer data concerning how energy is localized between antennas or electromagnetic objects, which is directly connected to the physics of complex systems and the matter of energy storage, transfer, and manipulations. The work utilizes some recent developments in which a spectral close to-field theory and also the antenna current Green’s operate formalism were proposed to research and describe general electromagnetic systems. The present formulation is developed in conjunction with the special MoM implementation to get various numerical illustrations and new field energy density footage combined with analysis of the physics of near-field coupling as revealed through the new results. The technique realized here will be simply integrated into existing full-wave solvers like MoM to produce systematic photos of near-field interactions and coupling with additional comprehensive and detailed data compared with conventional port parameters like the S-matrix. The tactic is suitable for applications like close to-field detection, energy transfer, and close to-field communications, besides its elementary importance for mutual coupling in antenna arrays normally.
