SUMMARY

The discussion focuses on the propagation of a 150MHz sinusoidal plane wave in air, oriented at 30 degrees with respect to the +x-axis in the x-y plane. The electric field (E-Field) is polarized parallel to the plane of incidence with a magnitude of 2 V/m. Participants address the challenge of visualizing the orientation of the wave and its representation, emphasizing the conventional counterclockwise (CCW) angle measurement starting from the +x-axis. The consensus suggests that the correct orientation is 30 degrees North of East.

PREREQUISITES
  • Understanding of electromagnetic wave propagation
  • Familiarity with sinusoidal wave characteristics

Homework Statement



A 150MHz sinusoidal plane wave propagates in air at 30 degrees with respect to the +x-axis in the x-y plane. The E-Field is polarized parallel to the plane of incidence and has a magnitude of 2 V/m.

The Attempt at a Solution



My only question is about the orientation. I can't figure out how to draw the picture! Click on the image below to see what I have now. Is one of these orientations correct?

there isn't anything given in the question to indicate that.

but because of the normal way we choose to represent the angles (CCW starting from the +x axis) I would choose to fo 30 degrees N of E
