Characteristic Mode Analysis for Coupled Systems
Characteristic Mode Analysis for Coupled Systems
This project initially focused on the development of an in-house method of moment solver. Using the solver, a theory of coupled characteristic modes (TCCM) was proposed to analyze how the interaction of the isolated elements' modes gradually conform into the coupled characteristic modes. later, the idea was used for various coupled environment analysis like antenna-antenna coupling, antenna-ground coupling and modelling of radiation exposure, etc.
