What are microwave systems?
A microwave system is a system of gear used for microwave data transmission. The typical microwave system includes radios located high atop microwave towers, which are used for the transmission of microwave communications using the line of sight microwave radio technology.
What is microwave communication system?
A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit video, audio, or data between two locations, which can be from just a few feet or meters to several miles or kilometers apart.
What are microwave antennas used for?
Microwave antenna is used for radiating microwave signal into space and receiving microwave signal from space. Microwave antenna acts as a transition region between free space and guiding structure like a transmission line in order to communicate between two or more locations.
What is the frequency range for microwave?
Microwave frequencies range between 109 Hz (1 GHz) to 1000 GHz with respective wavelengths of 30 to 0.03 cm.
What are the parts of a microwave?
Microwave Oven Components and their functions
- Transformer. Microwaves require a high voltage of power to adequately capacity and cook food.
- The Magnetron.
- A waveguide.
- Cooling fan.
- Cooking Case.
- The rotating disc/ Turntable.
- Control Panel/Inspection Window.
What is the physics behind microwave?
The magnetron generates microwave radiation by bouncing electrons around inside a vacuum filled cavity that is exposed to a strong magnetic field. This magnetic field forces these electrons to circle around inside the cavity, absorbing energy. Eventually, this energy is released as a microwave.
How does a microwave works?
Microwaves are produced inside the oven by an electron tube called a magnetron. The microwaves are reflected within the metal interior of the oven where they are absorbed by food. Microwaves cause water molecules in food to vibrate, producing heat that cooks the food.
What are the 3 main components of a microwave?
a cavity magnetron, which converts high-voltage electric energy to microwave radiation. a magnetron control circuit (usually with a microcontroller) a short waveguide (to couple microwave power from the magnetron into the cooking chamber)
How a microwave works step by step?
What is wavelength of microwave?
The microwave region extends from 1,000 to 300,000 MHz (or 30 cm to 1 mm wavelength).
How does electricity work in a microwave?
Inside the guts of a microwave, a device called a magnetron channels electrical energy from a power outlet to a heated filament, creating a flow of electrons that in turn transmits microwaves into the cooking chamber through an antenna.
What is the energy of microwave?
