It talked about vector spherical harmonics but did not answer my question.jedishrfu said:These classnotes may answer your question on what Jackson is gettting at:

Section 9-6 of Jackson classical electrodynamics is a chapter in the textbook written by John David Jackson. It covers the topic of electromagnetic waves and their properties.
Section 9-6 covers the concepts of Maxwell's equations, plane waves, polarization, and the energy and momentum of electromagnetic waves.
Section 9-6 builds upon the concepts introduced in earlier chapters, such as Coulomb's law, Gauss's law, and Ampere's law. It also serves as a foundation for later chapters, such as radiation and scattering.
Yes, the principles discussed in section 9-6 have numerous applications in various fields such as telecommunications, radar technology, and optics. They also play a crucial role in understanding the behavior of light and electromagnetic radiation in general.
This may vary from person to person, but generally, section 9-6 can be challenging due to the complex mathematical equations and concepts involved. However, with a strong foundation in electromagnetism and mathematics, it can be understood with dedication and effort.
