Electromagnetic waves radie antenna HELP

SUMMARY

The discussion centers on the behavior of electromagnetic (EM) waves in relation to antenna orientation. A student observes optimal reception of a radio-frequency EM plane wave when the antenna is positioned parallel to the x-y plane at a 60-degree angle to the y-axis. The electric field (E-field) is aligned parallel to the antenna, while the magnetic field (H-field) is perpendicular. The student questions whether reversing the wave's propagation direction from +z to -z alters the relationship between the fields and the antenna orientation, concluding that the polarization remains unchanged.

PREREQUISITES
  • Understanding of electromagnetic wave propagation
  • Knowledge of antenna theory and orientation
  • Familiarity with electric and magnetic field interactions
  • Basic concepts of polarization in EM waves
NEXT STEPS
  • Study the principles of electromagnetic wave propagation in different media
  • Learn about antenna polarization and its effects on signal reception
  • Explore the mathematical representation of electric and magnetic fields in EM waves
  • Investigate the impact of antenna orientation on reception quality in various scenarios
USEFUL FOR

Students in physics or engineering, radio frequency engineers, and anyone interested in antenna design and electromagnetic wave behavior.

Homework Statement


A radio-frequency EM plane wave propagates in the +z-direction. A student finds that her portable radio obtains the best reception of the wave when the antenna is parallel to the x--y plane making an angle of 60 degrees with respect to the y-axis .
(a) Consider an instant when the fields are non-zero at the location of the antenna.
Draw and lable the direction of the electric field and the direction og the magnetic field.Explain
(b)How would your answers to part a be different if the wave were propagating in the -z-direction.Explain


The Attempt at a Solution


a) i drew the E field parallel to the antenna and the b field perpendiculat to it so that the oscillation will be at a max...is this right?
b) i am unsure of what changes

I don't think anything changes if you reverse the direction between +z and -z.

The e and the h waves are still perpendicularly polarized with respect to the orientation of the antenna is my understanding.
