The spatial structure of quasi-circular waveguide Alfven modes at the plasmapause, whose existence is attributable to the presence of a minimum on the transverse Alfven velocity profile, is described by applying the WKB approximation method to a system of wave equations. Using the earlier hypothesis of Dmitrienko and Mazur (1985) that geomagnetic Pc1 pulsations are a superposition of Alfven waveguide eigenmodes, results are obtained describing the spatial Pc1 structure. By treating Pc1 as waveguide eigenmodes in the plasmapause, it is possible to explain why Pc1 pulsations are tied to the plasmapause, as well as the possibility of a multiple intensification of Pc1 pearls as they travel between the magnetoconjugate ionospheric regions.
