We consider a wedge geometry for a model of a nonuniform layered earth. The plane wave spectrum of a line source excitation is allowed to reflect successively at the nonparallel interfaces. The semiconvergent series is truncated when the lowermost image term has been accounted for. The partial sum, so obtained, is considered to give a useful approximation to the resultant fields. It is found that there is a significant dependence on the tilt angle of the subsurface interface.
