How could 2 crossed fields polarize and deflect EM radiation

Click For Summary
SUMMARY

The discussion centers on the concept of using two crossed fields to polarize and deflect electromagnetic (EM) radiation, as described in Arthur C. Clarke's 1953 novel "Childhood’s End." The idea posits that these crossed fields could theoretically block solar radiation from reaching Earth. While this concept is fictional, it raises intriguing questions about the principles of polarization and electromagnetic fields in physics. The discussion emphasizes that such phenomena do not occur in reality, highlighting the distinction between theoretical exploration and practical application.

PREREQUISITES
  • Understanding of electromagnetic radiation principles
  • Familiarity with polarization concepts in physics
  • Basic knowledge of field theory
  • Awareness of science fiction's influence on scientific ideas
NEXT STEPS

In the 1953 science fiction novel Childhood’s End by Arthur C. Clarke, characters use two crossed fields in outer space to block some of the solar radiation traveling towards earth: “Somehow, out in space, the light of the Sun had been polarized by two crossed fields so that no radiation could pass” (page 12, here's the link: https://books.google.com/books?id=d...ce=gbs_ge_summary_r&cad=0#v=onepage&q&f=false) I was wondering what is meant when Clarke writes that the radiation was “polarized by two crossed fields.” What are the ways that this effect could be achieved in theory (not necessarily in practice)? Also, I am studying first year college physics, and I am asking this question out of my own curiosity. Thank you very much.

This is pure fiction. This doesn't happen in reality.
