Body waves as normal and leaking modes—leaking modes of Love waves

B. J. RADOVICH* and J. CL. DE BREMAECKER

DEPARTMENT OF GEOLOGY RICE UNIVERSITY, HOUSTON, TEXAS 77001

Abstract

Dispersion curves of leaking modes of Love waves are computed for a one-layer crust-mantle model. The frequency and wave number are complex, but the group velocity is purely real. Group velocities well below the Airy phase of normal modes are found; waves with group velocities between 1.0 and 3.8 km/sec attenuate the least, but even these decay too much ever to be detected. There are no phase velocities between the velocity of the half-space and that corresponding to the Brewster angle.
