What is the dispersion relation for the Alfvén-ion cyclotron wave?

What is the dispersion relation for the Alfvén-ion cyclotron wave at arbitrary propagation angle?

I've looked in most of the textbooks. The ones that give any dispersion relation at all assume parallel propagation, or at minimum (in the case of Stix) propagation not too close to perpendicular. That assumption is not valid for what I have in mind.
