Transient Electromagnetic Wave Propagation in Waveguides

Kristensson, Gerhard LU (1993) In Technical Report LUTEDX/(TEAT-7026)/1-24/(1993) TEAT-7026.
Abstract
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... (More)
