A plane wave propagating along the positive z axis in vacuum is polarized along the y axis at a frequency of 3 GHz. Write the phasor of the E field, H field and Poynting vector.

Question

Isn't a phasor the same regardless of the field it is on? Like E, H or Poynting?
How can I compute the phasor?

Thanks!

Answer 1

yes, if it is polarized along one plane. you know of course, H, and Poynting are different directions.

Answer 2

I'm having trouble determining its directions, how can I find them?

You are so useful man, you can't imagine how grateful I am.

Thanks.
