Good job, jzagaja,
*if* - for one reason or another – you'd like to stick with that particular driver and do not like to take a ring radiator with sufficient displacement instead, I'd like to see a simu with the inner ring of that driver covered by a phase plug reaching out to the mouth of the horn - meaning you close and extend the middle phase plug .
In praxis you could make that phase plug hollow - slide it over the middle phase plug (the ring shaped one) - stuff it heavily, to absorb what's coming from the inner ring.
Sure - you will lose some of the active membrane area but not *that* much IMO (rough guess : 75% still active).
If simu is any good, you then could go on checking out if tweaking the contour of the looooong phase plug is worth the effort.

I don't think that you understand how a phase plug works. What you have drawn are all incorrect or if they are modeled from a real device are very bad designs. The cross sectional areas must be a smoothely varying continuos function of the propagation path and should conform to the waveguide flare all the back to the diapragm (which of course is never the case - they are virtually always conical). Yours do not do that, the cross section area changes abruptly at the end of the plug.
Yes, thats a poor design and I'm not in the business of redoing the designs for other people.
if you'd like, you could send me your AxiDriver file and I will demonstrate what I mean in converting yours into a ring radiator horn...

Better is to curve the chanels so that they attach normal to the connecting aperature, but that doesn't change the patent so they are not shown.

Yeah, with basic geometri and logic, that would be the way that makes sense
About equal areas, and compression ratios, I suppose

That looks wrong. The radial openings of the slot should be largest in the middle (like you have them) and smallest at the outside to have equal areas. You seem to have the middle slot being smaller than the outer slot.
If you after some specific details - a single high res simu may take you days on dedicated quad core even

First statement on paragraph "prior art" :
Uuups
Statement at 48 :
even for a noob its obvious that this is a requirement - such things can only go for patent in the country of "boundless possibilities"
Oh boy....
Together with the crude drawing zjagaja takes for a blue copy - stopped reading there ...
