Abstract :
A systematic procedure generalized to derive the variational expressions for electromagnetic and/or acoustic field problems is proposed. It is shown that the variational expressions useful to treat the systems involving electromagnetic waves or acoustic waves or both can be formulated systematically all from the simple and basic principle of least action point of view.
