These functions are derived as linear transformations of the manifold of EL eigenfunctions, aiming to minimize the spatial extension of each oscillet. Emphasis is placed on the adoption of these new functions in electrodynamic and electronic computations, particularly in the optimization of irregular ELs found in various microwave and optical sources, including those with open-ended configurations featuring a continuous spectrum of eigenfunctions. An illustrative example showing the utility of partial functions in the electrodynamic calculation of a longitudinally inhomogeneous EL is provided. |
