High-frequency spectrum was used since there was a limited number of users and applications.

Advanced communication and radar systems had bandwidth needs in the microwave range.

The rise in frequency resulted in a drop in wavelength.

12 to 18 GHz designation as L band.

NTRA established to allocate the available frequency spectrum among the many national and international scientific, industrial, commercial and government services who use it.

The electron in a magnetic field only moves in circular motion.

Advanced communication and radar systems had bandwidth needs in the microwave range.

Uniform plane waves are controlled by the following: the vectors E and H are both parallel to the propagation direction (z-direction).

Electromagnetic plane waves travel through free space in speed independent and different from speed of light.

Plane wave is a transverse magnetic wave (TM).

The uniform plane wave characteristics are useful in complex wave types that may be described as a superposition of plane waves.

Each plane’s normal to the wave propagation has the identical E and H magnitudes at every certain instant.

To define complex plane waves such as transverse magnetic (TM) and transverse electric (TE), we may utilize the uniform plane wave.

Uniform plane wave is the most basic form of electromagnetic waves; a fundamental type with specific characteristics that make them particularly useful for understanding.

If a negative charge for electron, the force will be in the opposite direction of the field.

Crossed fields refer to the simultaneous existence of electric and magnetic fields at right angles.

Wave reflection occurs when the load impedance matches the characteristic impedance of the line.
