Electromagnetic Wave Propagation

What is the orientation of the electric field vector in respect to the surface of the Earth?

What is the mathematical expression for the strength of a magnetic field (H) produced around a conductor?

What is the rate at which energy passes through a given surface area in free space?

What is the characteristic impedance of a lossless transmission medium equal to?

What is the imaginary line drawn perpendicular to the interface at the point of incidence called?

Semirough surface will reflect as if it were a smooth surface whenever the cosine of the angle of incidence is greater than λ/8d, where d is the depth of the surface irregularity and λ is the wavelength of the incident wave.

Modulation or redistribution of energy within a wavefront when it passes near the edge of an opaque object.

Diffraction occurs around the edge of the obstacle, which allows secondary waves to “sneak” around the corner of the obstacle.

States that the total voltage intensity at a given point in space is the sum of the individual wave vectors.

Electromagnetic waves travelling within Earth’s atmosphere.
