What is the significance of negative index of refraction in modern physics?

Click For Summary

Discussion Overview

The discussion centers on the significance of negative index of refraction in modern physics, particularly in relation to metamaterials. Participants explore resources, articles, and challenges in accessing relevant literature.

Discussion Character

  • Meta-discussion, Technical explanation

Main Points Raised

  • Some participants reference an article co-written by John Pendry, noted for his contributions to the field of metamaterials with negative index of refraction.
  • There are issues with accessing a specific PDF link related to the article, with multiple participants reporting errors in downloading the file.
  • One participant suggests that the error may be due to using an outdated version of Acrobat Reader and recommends updating to a newer version.
  • A later reply offers alternative resources, including a recent article by John Pendry and presentations by Vladimir Shalaev, which may be of interest to those researching metamaterials.

Areas of Agreement / Disagreement

Participants generally agree on the importance of the topic and the relevance of the referenced materials, but there is no consensus on access to the specific PDF or its contents.

Contextual Notes

Limitations include unresolved issues with accessing the PDF and potential dependencies on software versions for file compatibility.

This article is as good as any tutorial on the physics of negative index of refraction. It was co-written by John Pendry, who has been credited for inventing/discovering the metamaterial that exhibits this property.Zz.

When I downloaded the pdf, I got an error message from Acrobat 4.0 not being able to open the file.

Sounds like you have an old version of acrobat reader. Some new files cannot be opened by the older versions. You can update to a newer version from the adobe website for free.
 
hi there! sorry for the thread un-burial but does anyone have this file

http://www.physicstoday.org/vol-57/iss-6/pdf/vol57no6p37_43.pdf

or the access to physicstoday.org to get it?
i've started today the research on metamaterials and i could use the help on getting that file!

thx in advance!

Hi José, I don't have access to this particular file either, but you might want to have a look at John Pendry's recently published trend-article: http://physics.aps.org/articles/v2/95" .

Another presentation by Vladimir Shalaev that might be interesting for you:
