Just a thought for the user-posts, ie replacing what the user typed, not the word->url-replacement and ofcourse have overrides so some links are allowed (like to another post in the forum maybe)

oh, forgot a link.. http://wwwatnf.atnf.csiro.au/projects/mnrf2001/symposium2004/JSK.ppt some nice ideas that maybe we could use, and maybe some ideas to make us be able to make a multi-layer version even :)

That would depend on how large the focalpoint is so i think a basic horn-antenna (http://en.wikipedia.org/wiki/Horn_antenna) should suffice for the test.. About the focal-point... Think of it this way. When having center at DC 1.0 and outer layer at 2.0. When the radiowaves gets reflected at...

Did some more reading about this on another one of these sleepless nights... Not shure about this, but from my understanding it seems like if you dont use multiple layers you will get a larger focal-point when increasing the size of the sphere and this might be the problems that where noticed...

Really cool idea.. Have been reading about this for a few hours now.. One thing i came up on was that we also need to consider the Loss Tangent of the materials used. So, what type of things are out there that have a low loss tangent at the needed frequencies and has a temperature-stable...
