A bus waveguide is a type of waveguide structure used to guide electromagnetic waves, typically in integrated photonics or microwave communication systems. It serves as a shared transmission medium, allowing multiple signals to propagate simultaneously with minimal crosstalk. Bus waveguides are often designed to efficiently couple light or radio waves to and from various devices, such as lasers, detectors, and modulators. Their configuration can vary, including straight or bent geometries, depending on the application requirements.

What is the dominant mode in rectangular waveguide?
Rectangular Waveguide - TE10; (TM11 in case of TM waves) Circular Waveguide - TE11;
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
The waves which cannot be transmitted in waveguide are?
The waves that cannot be transmitted in a waveguide are those that have a wavelength longer than the cutoff wavelength of the waveguide. These waves are unable to propagate efficiently within the waveguide due to the cutoff phenomenon which restricts their transmission.
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.
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 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
When a wave travelling in air enters into a waveguide The phase velocity will increase?
When a wave enters a waveguide from air, the phase velocity will decrease. This is because waveguides typically have a higher refractive index than air, causing the wave to slow down as it enters the waveguide.
What company introduced the acoustic waveguide technology?
Bose.
Easily adjustable tuning component in a waveguide is?
stub
Which of the following is not a basic component of an emf emitter?
waveguide
