Wave-particle interactions play an important role in radiation belt particle dynamics. For the Earth's dipole magnetosphere,we determine regions of electron cyclotron resonance with various types of plasma wave. We call these regions resonance zones. The spatial extent of a resonance zone is controlled by the Doppler cyclotron resonance condition and the wave dispersion relation. For a given wave mode, a resonance zone depends on the wave frequency,electron energy,pitch-angle,and the local values of the electron number density and magnetic field. In order to take account of density variation along magnetic field lines,we adopt three different models for the spatial distribution of electron density inside and outside the plasmasphere. For subluminous waves including whistler-mode chorus,whistler-mode hiss,and electromagnetic ion cyclotron waves,we construct resonance zones for both field-aligned and oblique propagation with respect to the background dipole field. We also determine resonance zones for the superluminous (AKR) R-X, L-O, and L-X modes. Resonance zones are useful in analyzing electron dynamics in the inner magnetosphere, in particular in conjunction with ray-tracing studies and observed spatial distributions of plasma waves.
