SUMMARY
The phase stationary method can indeed be applied to complex functions, and it retains its designation as the phase stationary method in this context. The steepest descent method is a more general approach that can be considered an analogue to the phase stationary method when dealing with complex functions. For further clarification and references, users are encouraged to review the discussion by @blue_leaf77 from February 16, 2015, which elaborates on the relationship between these methods.
