Abstract
The Fourier series method was extended for the exact analysis of wave propagation in an infinite rectangular beam. Initially, by solving the three-demensional elastodynamic equations a general analytic solution was derived for wave motion within the beam. And then for the beam with stress-free boundaries, the propagation characteristics of electic waves were presented. This accurate wave propagation model lays a solid foundation of simultaneous control of coupled waves in the beam.
