Does an electromagnetic shield reflect?

Click For Summary

Discussion Overview

The discussion revolves around the behavior of electromagnetic waves when interacting with nanoparticles, specifically graphene, which is proposed as an electromagnetic shield. Participants explore whether these waves would be reflected back and the implications of having an infinite number of such shielded nanoparticles.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants inquire whether a pulse of magnetic wave sent towards a graphene nanoparticle would be reflected back, questioning the nature of the wave involved.
  • There is confusion regarding the terminology, with some participants asking if "magnetic wave" refers to an electromagnetic wave and whether the behavior would be similar to that of a mirror.
  • Participants discuss the scenario of having an infinite number of EM shielded nanoparticles and what that would imply for signal reflection.
  • One participant expresses frustration with the clarity of the questions posed, suggesting that the original poster should consider the comprehensibility of their inquiry.

Areas of Agreement / Disagreement

The discussion contains multiple competing views and remains unresolved, particularly regarding the definitions and implications of electromagnetic shielding and the nature of the waves involved.

Contextual Notes

There are limitations in the clarity of terminology used, particularly the distinction between "magnetic wave" and "electromagnetic wave." The concept of "infinite" in the context of nanoparticles is also not clearly defined.

Let say a nanoparticle (graphene) is electromagnetic shield. If we send a pulse of magnetic wave will it get reflected back. If it reflects can that be interpreted. And what happens if there going to be infinite EM shielded nanoparticles. Is that any kind signal which will reflects back from shielded particle?

What does that mean?

What is a magnetic wave? Do you mean an electromagnetic wave? In that case: like a mirror?

What exactly is infinite here?
 
Well if particle is shielded with EM shield and if we going to send radio or gamma wave does it going to reflect back
 
Well if particle is shielded with EM shield and if we going to send radio or gamma wave does it going to reflect back. Infinite (lot of nanoparticle dispersed in water)

That's not a word. It's not even slang. It's just baby talk.

Nothing you have written is comprehensible. I suggest you think about it from the perspective of your reader and see if you make your question clear in her mind.
