Query: The Bible for Ultrasound Beamforming

This is probably my favorite text book of all time. Dr. Goodman's writing is excellent, providing heuristic insight into complex concepts using a very readable style. He is the Richard Feynman of optics.And other than chapters specific to polarization, this book is entirely applicable to phased array ultrasound. For anyone whos works or studies in the ultrasound field, this book is a must, especially if you have an interest in acoustic beamforming. All the wave and Fourier concepts that apply to light also apply to ultrasound.
