Propagation of transient electromagnetic waves in inhomogeneous and dispersive waveguides

På svenska

Author

Summary, in English

Transient wave propagation in a waveguide filled with an inhomogeneous dispersive

medium is analyzed. The waveguide is inhomogeneous in the longitudinal

direction, but is homogeneously filled in the transverse directions. The

analysis is performed in the time domain and is based upon a wave splitting

technique and the method of propagators. The propagator maps the exciting

field from one position in the waveguide to the field at another position. This

mapping is represented as time convolution integrals. The theory is exemplified

by numerical examples where it is shown how wave trains of different

shapes are propagating in a waveguide filled with a homogeneous dispersive

medium.
