# A real frequency, complex wave-number analysis of leaking modes

@article{Watson1972ARF, title={A real frequency, complex wave-number analysis of leaking modes}, author={T. H. Watson}, journal={Bulletin of the Seismological Society of America}, year={1972}, volume={62}, pages={369-384} }

Leaking-mode dispersion and attenuation is computed for two single-layer models. Roots of the dispersion relation are obtained in the complex wave-number plane, using real frequency as the independent variable. At low frequencies the root loci on the (+, +) sheet determine the fundamental propagating mode plus a series of attenuated standing-wave modes in the vicinity of the source. As frequency increases, the complex roots on all four sheets migrate through the wave-number plane, producing… Expand
