There are two groups of microwave devices. Semiconductor Devices, Tube Devices
Microwave refer to high frequencies (above 300MHz) and short wave lengths, at the microwave components depends on the changing
The Traveling-wave tube can be used as a medium or high power microwave, amplifier. The TWT, because of its construction and working
The travelling wave MASER (T.W.M) consists of a wave guide structure in wh
A maser is a device that produces coherent electromagnetic waves through amplification by stimulated emission.
The Magnetron is a high power microwave oscillator, uses the interaction of electric and magnetic fields in a cavity to produce oscillations of very high power.
We know that a body which absorbs all kind of radiation falling on it is called black body.
The lasers having gas as an active medium is called gas lasers. Generally there are three classes of gas lasers.
Detectors are device used with lasers to detect or discover the presence of something. There are two categories of the detectors
The Q-Switch is a device which is placed inside the laser cavity. Main purpose of the Q-switch is to rapidly change the feedback of a laser cavity from minimum to maximum.
