A Variational Rayleigh–Ritz Method for Modeling H-Plane Bend Rectangular Waveguides

Abstract: This article introduces a novel variational formula for modeling waveguides with uniformly curved longitudinal axes. Using the Rayleigh-Ritz method, we analyze the electromagnetic fields in ...

On the application of the Rayleigh–Ritz method to a projected Hamiltonian

We apply the well known Rayleigh–Ritz method (RRM) to the projection of a Hamiltonian operator chosen recently for the extension of the Rayleigh–Ritz variational principle to ensemble states. By means ...

The Inverse Sturm-Liouville Problem and the Rayleigh-Ritz Method

In this paper we present an algorithm for solving the inverse Sturm-Liouville problem with symmetric potential and Dirichlet boundary conditions. The algorithm is based on the Rayleigh-Ritz method for ...
