Propagation of transient electromagnetic waves in inhomogeneous and dispersive waveguides
Författare
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.
