Resonance zones in the Earth's dipole magnetosphere are determined for electron cyclotron resonance with obliquely propagating very-low-frequency chorus, extremely-low-frequency hiss, electromagnetic ion cyclotron, and magnetosonic waves. The resonance zones, which are presented in (L,lambda) space, where L is magnetic shell and lambda is magnetic latitude, depend on the assumed particle density distributions inside and outside the plasmasphere, the specified wave bands, and the electron kinetic energy. This work is a companion paper of Ni and Summers [Phys. Plasmas 17, 042902 (2010)], which considers strictly field-aligned wave propagation. Inclusion of the wave normal angle parameter adds an extra degree of freedom to the calculations, and emphasizes the need for global observational data on the wave spectral properties. Comparison of resonance zones with global wave distributions is a useful aid in the modeling of radiation belt electron dynamics. Resonance zones are also of potential use in the interpretation of observational data on particles and waves at given points in space.
