| Abstract: | In the paper, according to Maxwell's equations, the expression of the principle of least action has been derived by the theory of imaginarx work, and the functional expressions for the electromagnetic field problems, for instance, a resonant frequency, a propagation constant, and an impedance of the waveguide junctions etc. are derived all from the principle of least action which is considered as unified variational theory.Three expressions are very useful in the microwave and optical waveguides techniques. |
