The fundamentals of this have been well known since the earliest days of telephony (19th century). I put this tutorial together about 20 years ago, inspired by Jim Hayward's work, cited as a reference. The Moore text, cited as a reference, had a lot of detail about the development of practical long underwater cables, including measures to minimize the effects of the variability of VF with frequency.
