TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. In hollow waveguides (single conductor), TEM waves are not possible, since Maxwell's Equations will give that the electric field must then have zero divergence and zero curl and be equal to zero at boundaries, resulting in a zero field.

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.
Why TEM waves cannot propagate in a wavwguide?
In a waveguide, transverse electromagnetic (TEM) waves cannot propagate because they require both electric and magnetic field components to be present and perpendicular to the direction of propagation. In a waveguide, the fields are constrained to be transverse to the direction of propagation, which is not possible for a pure TEM wave.
What is cutoff wave number?
The cutoff wave number is the maximum wave number that can propagate in a waveguide or transmission line without attenuation or loss. Waves with wave numbers higher than the cutoff wave number will be attenuated and cannot propagate effectively. It is an important parameter in the design and analysis of waveguides and transmission lines.
What type of wave requires a medium to propagate and cannot travel through a vacuum?
The type of wave that requires a medium to propagate and cannot travel through a vacuum is called a mechanical wave.
What wave can not propagate in vacuum?
Sound waves cannot propagate in vacuum because they require a medium to travel through such as air, water, or solids. Sound waves propagate through the vibration of particles in the medium, so without a medium to carry the vibrations, sound waves cannot travel in vacuum.

What is difference between Rectangular Waveguide and Circular Waveguide?
circular is easy to manufacture than rectangular As the name indicates the circular is circular in shape and rectangular is rectangular in shape its uses same modes that is Te and Tm I know this much only hope this helped u little bit atleast A: In principle waveguides act as the equivalent of wires for high frequency circuits. For such applications, it is desired to operate waveguides with only one mode propagating inside of the waveguide. With rectangular waveguides, it is possible to design the waveguide such that the frequency band over which only one mode propagates is as high as 2:1 (i.e. the ratio of the upper band edge to lower band edge is 2). With circular waveguides, the highest possible band width allowing only a single mode to propagate is only 1.3601:1. I found it on Wikileaks.

Waves with wave numbers higher than the cutoff wave number will be attenuated and cannot propagate effectively.

How is a cube and a rectangular alike?
They are not - mainly because there is no such thing as a rectangular. "Rectangular" is an adjective, not a noun and therefore a rectangular, by itself, cannot exist.They are not - mainly because there is no such thing as a rectangular.

What is the sum of interior angles of a rectangular pentagon with eight sides?
You cannot have a rectangular perntagon. A rectangular shape cannot have eight sides. A pentagon cannot have eight sides. Consequently, this question cannot be answered.

What is the diameter of a rectangular field of 1km?
A rectangular shape cannot have a diameter, which is a characteristic of a circle.
Can sound travel through a vacuum, and if so, how does it propagate in the absence of a medium?
No, sound cannot travel through a vacuum because it requires a medium, such as air, water, or solids, to propagate. In the absence of a medium, there are no particles for the sound waves to travel through, so they cannot propagate.
How many edges does a rectangular triangle have?
A rectangular triangle is an oxymoron! A triangle cannot be rectangular and no rectangular shape can be a triangle. The two words contradict each other.
Are the triangles on the rectangular pyramid equal?
No, they cannot be.
