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
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 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.
A clock has hands but cannot wave.
My answer is NO, since vibrating electric charge cannot exist independently (conservation of electric charge cannot be violated). Vibrating electric charge can only exist as part of electric charge wave.
Attenuation is when a wave is dampened inside a soft boundary. This occurs when the energy of the wave is absorbed or dissipated by the material of the boundary, causing the wave to decrease in intensity.
Arif Ullah khan utman kheel this is because for conductor E parallel is zero this means that the surface of the wave guide is at equipotential and this potential follow the laplace equation .it means that there is no maxima and minima inside the wave guide . this means that the electric field inside zero . hence the TEM do not exist in wave guide only TE and TM can be exist . if we place some conductor in the wave guide then the conductor inside will not be equipotential and the TEM waves can be exist . like in Coaxial cables

No, it's not. EM wave is a single unit, and it cannot exist without ether of components (electric, magnetic).

yes war of the worlds 2 the next wave exist
A clock has hands but cannot wave.
The S Wave (Secondary Wave) cannot travel through water. On the P Wave (Primary Wave) and the Surface Wave can travel through water.
get your tour guide hat on and wave

first we must ask our selves do these waves really exist?
