Need reference on RF simulation algorithms

I am searching for any online reference (thesis, ebook) that will cover the basics on RF simulation algorithms such as Harmonic Balance, Shooting, Fast algorithms etc.
Any input is appreciated.

You may look at "Introduction to RF simulation and its application" on this site:
http://www.designers-guide.com/Analysis/

This book has harmonic balance among other topics:
