I have some (well a LOT) of microwave absorber. it looks like a mix of ferrite and rubber that has been bonded to a stainless steel cloth (think window screening) in the middle. About 1/8" thick.
I can get the make, p/n and a picture this weekend if interested. I remember the company that made it got bought out, which then got bought out etc and I gave up. Price would be free+shipping, there are about 400 each sheets about 30x30 inches. Each sheet must weight 5 lbs. > > > On 8/14/09 9:13 AM, "Mark Sims" <hol...@hotmail.com> wrote: > >> > >> >> Some of the data collection runs that I want to do is with the patch >> mounted >> on a pizza pan and in a cake pan and see if that helps the performance >> by >> faking what a survey antenna does. >> > > If you can scrounge up some suitable RF absorbing material to put on the > pan, that might be an interesting experiment.
