It is oftimes said that parasitic elements of a yagi absorb
radiatiation
and then reradiate half of what it received. Is this meaning that it
only absorbs half of the radiation applied in its direction and where
it
then reradiates 100% of its radiation? It apears to be a simple
question
depending how one looks at it in terms of efficiency which could mean
anything.
Now in my unreleased Gaussian antenna array there is no interaction
with respect to radiation as radiation cannot occur outside until the
enclosed border is breached.
On the face of it one then can assume that a yagi is not really
efficient depending how one uses terms that have a special definition
because of absorbed radiation.
Thoughts! Auguments!. Trashing, or what ever trips your trigger.
Just when you thought that Gaussian arrays would go away a thing like
this comes along,
go figure. ( Don't forget Pointings vector and what it implies.grin)
