Abstract
A method of analyzing an electromagnetic wavefield includes the steps of measuring the electric and magnetic fields at at least one receiver, formulating a respective spatial domain filter in respect of each of mutually orthogonal components of each of the electric and magnetic fields, and applying the filters to the measured acquired data to decompose the wavefield into upgoing and downgoing components.
