Echosorb, a popular microwave RF absorbent material that is available in sheet form. It ranges from a 1/16" thick pliable rubber to thicker, multilayer foam that looks like the black antistatic foam used to ship IC's and other semiconductors. Hi Mike, It is also quite heavy which would be inappropriate for aviation applications. I played with this stuff a dozen years ago when one of my buddies got a speeding ticket in his 'Vette. He asked me to design a stealth bra for his ride - it didn't seem to be practical for any of several reasons. 73's Richard Clark, KB7QHC |

Until I saw the price. Cheaper to pay the tickets ;-) Jack |
The 297 hits on Google for "radar absorbent material" was information overload? The 3,730 hits for "RF anechoic material" frightened you? And the 70,100 hits for "stealth aircraft design" sent you scurrying here to see if we had anything for you? At least it's nice to see you doing your homework before Sunday night. Ed wb6wsn Wow. Good thing Frank is a seasoned ham; had he been a newbie you would have just chased him from ham radio. Congratulations, Elmer! Al W6LX |

"J. Kraus shower that space cloth of this impedance reflects 30 percent of the incident wave." There must be an impedance discontinuity. Not 377 ohms? Kraus said sheets of space cloth backed by a reflecting plate are sandwiched between plastic layers. Kraus has an appendix "D" on absorbers. Searching on "Salisbury screens" got me 4578 hits.

Al W6LX Don't be an apologist for people who ask stupid or ill-phrased questions. Don't pander to the lowest level. I provided a reply which I thought was appropriate to the question. It was slightly sarcastic, though, by Usenet standards, reasonably civilized. It provided three direct lines of search for what was a very nebulous and obvious query. At no point did I attack the poster, demean his mentality, question his civilization, or impugn the length of his manhood. Further, I hope your self-worth is well seasoned, or at least insulated, as you don't seem to understand the difference between Usenet and Ham Radio. Cranking off a dumb query on Usenet is equivalent to tuning up on a repeater or net frequency. It's a bad use of electrons, and you can expect to be chastised. Perhaps I shouldn't be so harsh with you, as you can't seem to follow the thread. If you were, you would have noticed that I provided considerable background on RF absorbent material in a subsequent post. Now, do YOU have anything informative to add to the subject, or are you just trolling for sympathy? BTW, in addition to being in the dictionary, "sympathy" yields about 3,700,000 hits on Google. Now there's a project for your dotage. Ed wb6wsn |

You should get a job at a community college, Ed. College students are inured to your particular brand of snide, demeaning discourse, since many teachers use it as a technique for avoiding having to answer questions requiring knowledge those teachers don't possess. 73, Tom Donaly, KA6RUH |

Oh, the horror! Whatsa matter Tommy, did I hit a button on you? Some jackass community college teacher give you a low grade, and it ruined your life? Nothing left for you but trolling Usenet? So here's my challenge to you, Tommy Twerp. Either add something useful about RF absorbent materials, or go fellate an operating 5U4! Ed wb6wsn |
