More context would have been interesting.

While you could use equation 1.100 with complex numbers (the mathematics is fine) it doesn’t make sense in the context that we don’t see - only real values are meaningful.

You must provide more detail about the context of the passage you quoted. What situation is "the geometric situation being described"?

Thank you I understood it
