Hi,
As the part of a science project, I'm trying to refract communicational radio-waves towards a point. I first thought about using a lens, but because of double refraction when passing through a lens, relatively little refraction is achieved. I thought that if I could create a bubble of some refractive yet transparent materi9al and place the receptor inside this bubble, then the waves would continue to get refracted without reverse refraction, thereby enabling me to achieve higher refraction.
I wish to know if I've got refraction right. Am I thiunking rightly?
Beside that, can you possibly tell me the possible refractive limit of a lens that's not too expensieve(not observatory quality, something that can be afforded by a ordinary man)?
If the bubble theory is wirkable, what substance should I use as the material for my bubble?
To clarify my points, I've uploaded two pictures of the two concepts at http://loom91.tripod.com/lens.jpg and http://loom91.tripod.com/bubble.jpg. Pls take a look at them.
Thanx to you all for help.
