what is the shape of a transmission filter?

Usually flat and thin . They come in many shapes, designed for a specific transmission

The answer is: no.\n\nIt is not the shape of the lens that is important. It is the speed of the propagating wave in the medium in the lens relative to its speed in the medium outside the lens. \n\nConvex lenses made of glass in air focus rays of light. That is because light travels slower in glass than in air, so it is bent and becomes focussed. \n\nIf a convex lens was made of a material in which light travelled fast, and this was immersed in a medium in which light travelled slower, then it would not focus the light, but defocus the light. \n\nSuppose that one had a convex lens of rock, and the propagating wave was sound in air. Since sound travels through rock faster than air, the convex lens of rock would defocus the sound.

I would expect it to be square planar. What's interesting is that the trans effect was discovered on experiments involving platinum complexes, in the 1950s.

It's a DirectShow filter.

search for a trans receiver system operating in 2.4 GHZ  ism band ,,,, no licences required for this band for a transmitter of power less than 1 watt

Rod shaped? Are you referring to something like a 1N914?  \n\nThe "rod-shape" is the glass packaging.  The diode itself is only 625 micrometers thick and cannot be connected to electrically without the original metallization and bond wires.

As mechanical engineer this is out of my normal field but felt you deserved an answer of some sort.\n\n"Because of diffraction effects caused by slits or apertures in optical measurement systems, the radiation energy which is directed towards a particular region on a sample will be spread over a larger area than desirable. By employing an apodizing filter in the radiation path in such system, diffraction tails of the system will be reduced. The apodizing filter preferably has a pattern of alternating high transmittance areas and substantially opaque areas where the locally averaged transmittance function is an apodizing function. In the preferred embodiment, the locally averaged transmittance function varies smoothly and monotonically from the periphery to the center of the filter"\n\nI see the theory here, also found on on using an apodizing mirror to stabalise images in a telescope\n\n"I built and used an apodizing screen for my 6" f/8 scope many years \nago. I made it by layering several layers of window screen, each one \nwith a circular cutout of different diameter. The result was an aperture \nmask with a step-wise approximation to a smooth apodizing function. It \nwas claimed to improve contrast for planetary viewing. Anyway, my \nexperience was that it seemed to make the image more stable but if it \nimproved contrast, I couldn't see it. If you do this on-axis, the \ndownside is that your diagonal mirror will now become more of a factor \nin the contrast equation. The bottom line is I wouldn't recommend it."\n\nAlso "An excellent reference for all sorts of technical techniques is\n>"Procedures in Experimental Physics" (also printed under the title\n>"Physical Laboratory Practice") by John Strong.  I don't recall the\n>publisher, but it came out in the 30's.  The bad news it that it's been\n>out of print for decades (and some SOB stole the copy I got from my\n>father!); the good news is that an outfit called Lindsay is reprinting it\n>in paperback.  (Don't have their name/address here in the office; I'll try\n>to remember to look it up tonight.)\n>\n>                            Dr. Kurt Hillig\n\nEvery ATM should have a copy of this great book. Lots of stuff on\nmirror making, figuring, special laps,making flats, prism ,etc.\nThere is nice modifed Draper machine ( upper disk also powered)\nand a homemade diamond cutting wheel to cut small glass blocks.\n( I would like to build this one someday ) A great section on\nkinematical mechanical construction. Yeah this a mid 30,s book but the \ninfo\nstill can be used. No I don't work for Lindsay Publications,<G>\n\nBob Pfaff\n\n\n This book, in paperback form, can be ordered from\n      http://www.amazon.com, on the Web. It can also be ordered\n      through your local bookstore. Amazon prices it at $23.95, and\n      provides the following information:\n\n      Published by Lindsey Publications\n      Publication date: June 1986\n      ISBN: 0917914562"\n\nSorry couldn't find any really decent expplanations, but at least you've got a starting point.

You could use the circle to crop the earth map image and then apply the "bubble" or "sphere" distortion filter to it.  It won't be a real 3d spherical map of the earth, but it may look similar if you are patient.

The dish antenna used for satellite communication.  The parabolic shape focuses the incoming signal onto a single point where it can be detected, amplified, and routed to the end user.\n\nA magnifying makeup mirror.  The shape causes light rays reflected off your face to strike the mirror and reflect off that mirror at a slightly different angle.  That particular reflection will strike your eyes in such a way as to make your face seem larger.  The larger it appears the easier it is to determine precisely where to apply makeup.  In addition, it can free a person from needing glasses to apply makeup, thus removing an obstruction to applying that makeup.
