- Abstract
- An explicit variational principle for the propagation constant of guiding structures is compared to the finite-element method using a functional involved in the explicit variational principle formalism. Values of the propagation constant yielded by the finite-element method are shown to be stationary about the discretized field. Comparative;e results show how the convergence is influenced by the differing nature of the explicit unknown (field for finite elements, propagation constant for the explicit variational principle).
