Difference between light scattering and radiowave scattering.

Click For Summary

Discussion Overview

The discussion centers on the differences and similarities between light scattering and radio wave scattering, exploring the principles behind each and their applications in different contexts, particularly in relation to concrete surfaces.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants suggest that light scattering and radio wave scattering operate on the same basic principles but differ significantly in length scale.
  • One participant requests examples of calculating scattering for light and 2.4GHz RF on concrete walls, indicating a desire for practical comparisons.
  • Another participant questions whether concrete is transparent at 2.4GHz, proposing a different comparison involving light reflection from glass versus microwave reflection from concrete.
  • A participant expresses a need for information on the parameters required to calculate scattering, mentioning the use of a light model for radio wave propagation.

Areas of Agreement / Disagreement

Participants generally agree that there are fundamental similarities in the principles of scattering, but there are multiple competing views regarding the specifics of calculations and the properties of materials at different frequencies.

Contextual Notes

There are unresolved assumptions regarding the transparency of concrete at 2.4GHz and the specific parameters needed for scattering calculations. The discussion also reflects varying levels of familiarity with the topic among participants.

Is there a difference between light scattering and radio wave scattering or do they operate on the same basic principles?
 
Engineering news on Phys.org
The basic principles are the same. The only real difference is in the length scale (which from a practical point of view of course makes a huge difference).
 
Can you give me an example on how to calculate scattering for these 2,

1- Light on concrete wall.
2- 2.4Ghz RF on concrete wall.

The comparison would help me understand much better.

Thanks.

Hope it's not a homework problem! However, isn't concrete fairly transparent at 2.4GHz? Perhaps you mean this: light reflection from glass surface, versus microwave reflection from concrete surface.
 
I just need to know how to calculate the scattering. What parameters are needed to calculate. I am using a light model to graphically show radio wave propagation.
