I have searched around the Internet for a definite definition of where the transition
between near filed and far field lie. I see a lot of rules of thumb, and they vary from something like
lambda/4 to 10*lambda. There has to be a truly technical definition that the measurement standard houses
use. If would appreciate it if you could point me to one or more documents that declare ye verily this
be the standard
Thanks, and have a good day.
