The radiation pattern of a corrugated-horn is given by the function
g(?) = P1v(cos?)/sin? + dP1v(cos?)/d?
where
P1v(cos?)
is the associated Legendre function of the first kind and order v.
The problem is determine its order v.
I know that to find v I have to use g(?m) = 0, where ?m is the max angle (horn flare angle). If ?m = 20º or any other angle, how could I find the order v in a way that g(?m) = 0 ???
Someone can help me with a tip or a reference?
Thanks any help...
