Hi All
It's easy to produce an E (electric) field and It's equally easy to produce an H
(magnetic) field. However, it is quite difficult to "convince" these two
separate fields
to join and create a Poynting vector unless, of course, someone invents a
"Poynting
director electrode" that can be added to the CFA design ;-)
The Poynting vector is the cross product E x H and it points in the direction of
energy transfer (in case of EM wave).
I remember reading an article which proved, mathematically, that the CFA
simply does not work. (Unfortunately, I do not remember which publication)
After reading about the CFA, I have to confess that I do not believe in it.
(the free lunch stuff again...)
