✦ Synopsis

This paper deals with the construction of discrete numerical solutions of mixed problems for the telegraph equation. After discretization, the two-variables partial difference mixed problem is solved by means of a discrete eigenfunctions method that mimics the advantages of the continuous eigenfunction method while eliminating its computational disadvantages. The solution is based on a closed form solution of the inhomogeneous second order difference equation without increasing the problem's dimension.

A new wa¨elet-based technique to calculate radiating patterns by the FDTD method is presented. This technique has been applied to the study of a microstrip patch antenna. Results show a substantial gain both in memory storage and CPU time, while maintaining the same accuracy as the classical computa

Two computer programs (FGHEVEN and FGHFFT) for solving the one-dimensional Schrodinger equation for bound-state eigenvalues and eigenfunctions are presented. Both computer programs are based on the Fourier grid Hamiltonian method (J. Chem. Phys. 91(1989) 3571). The method is exceptionally simple and
