So the design changed slightly from what Kunysz reported in whis two papers [1,2] back in 2000... I wonder what this small, detached stripe at the end of the "spokes" does. It's not mentioned in the papers. But [2] shows some bragg reflector or something similar at the outer perimeter (i guess to have a similar effect as a choke ring), maybe those stripes replaced those.
