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 else can I help you with?
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 wave cannot propagate thorough a rectangular waveguide?
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.

Why the both electric and magnetic field are don't exist in the direction of wave propagation in tem waves?
In TEM (transverse electromagnetic) waves, the electric and magnetic fields are perpendicular to each other and perpendicular to the direction of wave propagation. This is because the wave is designed to have components that oscillate in orthogonal planes, allowing the wave to propagate without the need for a medium to carry it.
Which wave cannot exist inside wave guide?
TEM TE modes (Transverse Electric) have no electric field in the direction of propagation. * TM modes (Transverse Magnetic) have no magnetic field in the direction of propagation. * TEM modes (Transverse ElectroMagnetic) have no electric nor magnetic field in the direction of propagation. * Hybrid modes are those which have both electric and magnetic field components in the direction of propagation
Name three types of electromagnetic waves?
I'll just quote "Fields and Waves in Modern Radio", by Ramo/Whinnery, 2nd edition, page 318: 1. TEM (transverse electromagnetic waves), 2. TM (transverse magnetic waves), 3. TE (transverse electric waves).

Why tem mode is not support in rectangular waveguide?
The transverse electromagnetic (TEM) mode cannot propagate in a rectangular waveguide because it requires both electric and magnetic fields to have no component in the direction of propagation. In a rectangular waveguide, the boundary conditions imposed by the walls necessitate that at least one field component must be longitudinal (along the direction of propagation) for any mode to exist. Thus, only transverse modes (TE and TM) can propagate, as they support fields that are entirely transverse to the direction of wave travel.

Can live specimens be used in a TEM microscope?
Live specimens cannot be used in a transmission electron microscope (TEM) as the high vacuum environment and electron beam would quickly kill any living cells. Instead, biological specimens must be fixed, dehydrated, and stained prior to imaging in a TEM.
How are electromagnetic waves generated and propagated?
Electromagnetic waves (those that can transmit their energy through a vacuum) have both an electric and a magnetic component. They are created by a vibration of charged particles. When passing through a medium, they are propagated by absorption and reemission of the wave energy by the atoms in the material.
