As shown in the given diagram the field pattern of electromagnetic waves is such that electric field is perpendicular to the magnetic field and both the fields are perpendicular to the direction of
When the electromagnetic waves are propagated from the transmitter antenna, it travels in a free space, up to receiver antenna.
There are the following characteristics of electromagnetic waves.
Field of Electromagnetic wave
There are two fields of the electromagnetic waves
When the alternating current passes through a wire than it sets up an electromagnetic field that propagate away from the wire.
The Q factor of the cavity resonator is the ratio between the stored energy of the cavity to the power loses in the cavity.
We know that laser generates light that has all the characteristics of ordinary light, However there are three important distinct characteristics of laser light that make it different from other or
About the nature of light there are two/three theories have been recognized.
As shown in the given diagram. The multi cavity klystron consist of a glass envelope in which there is an electron gun composed of heater and cathode.
There are two groups of microwave devices.
Microwave refer to high frequencies (above 300MHz) and short wave lengths, at the microwave components depends on the changing electromagnetic fields instead of current in the conductor or voltage
The Traveling-wave tube can be used as a medium or high power microwave, amplifier. The TWT, because of its construction and working principle has enormous bandwidths and low noise.
The travelling wave MASER (T.W.M) consists of a wave guide structure in which the wire figure or comb is designed.
