What is the dominant mode in rectangular waveguide?
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;
When is it advantageous to use a circular waveguide?
Circular waveguides offer implementation advantages over rectangular waveguide in Calculations for circular waveguide requires the application of Bessel.
What is variable attenuator?
A variable attenuator is a device used to adjust the signal strength of a radio frequency or optical signal. It can be used to reduce the intensity of the signal by an adjustable amount to prevent overloading or distortion in the receiving equipment. Variable attenuators are commonly used in communication systems, test and measurement equipment, and audio systems to control signal levels.
Why must the air inside a waveguide be dehumidified?
Moisture in the air in a waveguide can scatter the microwave energy the waveguide is designed to transport. This translates into signal loss or attenuation. The VSWR drops, and that is not a good thing.
What are the Differences between horn antenna and waveguide?
waveguide is a metal pipe that contains and guides microwaves from place to place in a microwave system (e.g. oscillators, amplifiers, mixers, modulators, filters, antennas)horn antenna has a waveguide connected at its focus, in transmit mode the waveguide feeds the horn which then emits a microwave beam, in receive mode the horn collects a microwave beam and concentrates it int the waveguide
How horn antenna is fed?
Horn antenna are typically fed by a section of a waveguide, the waveguide itself is often fed with a short dipole.
What is group velocity in waveguide?
Group velocity in a waveguide is speed at which EM energy travels in the guide.It will always be less then speed light.
What is a waveguide when referring to electromagnetism?
A Waveguide when referring to electromagnetism can point to any linear structure that transports electromagnetic waves in between the endpoints of the structure.
Which antenna is best guided by waveguide?
horn
What mode is less attenuation in circular waveguide?
TE10
What company introduced the acoustic waveguide technology?
Bose.
Easily adjustable tuning component in a waveguide is?
stub
