Discussion Overview

The discussion revolves around the feasibility of using a bubble made of a refractive material to enhance the refraction of radio waves for a science project. Participants explore the concepts of refraction, alternative methods for directing radio waves, and the materials that could be used for such a bubble.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant proposes using a bubble of a refractive material to achieve higher refraction of radio waves, questioning the validity of this approach and seeking advice on suitable materials.
  • Another participant suggests that a wire grid might be necessary for effective refraction of radio waves.
  • A different participant recommends using a waveguide tailored to the specific frequency of the radio waves being utilized.

Areas of Agreement / Disagreement

Participants present multiple competing views regarding the best method for refracting radio waves, indicating that the discussion remains unresolved.

Contextual Notes

There are limitations regarding the assumptions about the effectiveness of the proposed bubble method, the specific requirements for the wire grid, and the suitability of waveguides for different frequencies.

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.

I think you might need a wire grid to refract radio waves.

A wire grid?/
 
Why don't you just use a waveguide for the specific frequency of radio you're using.
