This paper focuses on propagation of transient electromagnetic waves in waveguides

of general cross section with perfectly conducting walls. The solution of

the transient wave propagation problem relies on a wave splitting technique,

which has been frequently used in direct and inverse scattering problems during

the last decade. The field in the waveguide is represented as a time

convolution of a Green function and the excitation. Some numerical computations

illustrate the method. Anew way of calculating the first precursor

in a Lorentz medium is presented. This method, which is not based upon

the classical asymptotic methods, gives an expression of the first precursor at

all depths in the medium. The excitation of the waveguide modes for time

dependent sources is also addressed.
