Effect of Earth’s Magnetic Field on Wave Propagation

Antenna & Wave Propagation

1. The average magnetic field of the earth is about 40 A/m. The earth’s magnetic field causes the electrons to trace complicated trajectories with cyclotron or gyrofrequency fg = l.4 MHz at H = 40 A/m. 2. The earth’s magnetic field (B) exerts a deflecting force on the moving electrons. The magnitude of this force […]

Effect of Solar Activity on Wave Propagation

Antenna & Wave Propagation

1. The output of the sun in all forms, light, solar wind and energetic particles is not constant. It varies with both time and position of the Sun. These changes are called Solar Activity. 2. The condition of the Sun has a major impact on ionospheric radio propagation. 3. As the Sun provides the radiation
