The diagram illustrates two reflectors in series. It seems to me, two reflectors set at precisely 90 degrees perpendicular would reflect any given signal back to its source, (the same as how bicycle reflectors work...) For example, if the City of Seattle put two reflectors on the Space Needle, any tenant, in any highrise could point a parabolic antenna at this reflector the reflected beam would paint all the windows on their side of their own building. And, all the *far* sides of all buildings along the line of sight...hmmm. Another application of reflectors: if A) you have some arbitrary hilltop or rooftop where one reflector could be installed and B) you have any number N of nodes you need to connect, it seems to me, you *might* be able to set the reflector to serve more than one path very nicely. perhaps many paths. Well, I guess this depends on how much power is lost in each bounce... TOdd At 09:36 AM 9/20/2002, Tim Pozar wrote: >Yup...
