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.

What is Equipotential lines in electric field?
Equipotential lines are lines that are perpendicular to the lines representing the electric field of a particle. A particle can travel freely of equipotential lines without doing any work.
What is the charge density for a conductor?
The charge density inside a conductor is always zero
Can a person stay safely inside a spherical conductor charged to a very high voltage?
Yes. The static electric field inside a charged conductor is zero, no matter what the voltage is between the conductor and the rest of the world.
Can two different equipotential lines cross each other?
No. If two equipotential surfaces intersect, then there would be two values of electric potential at the point of intersection, which is not possible.
Why TEM modes does not exist in wave guides?
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
Why TEM wave is not supported by hollow waveguide?

What instrument measures the electric equipotential?
Multimeter is an instrument that measures electric equipotential. Equipotential lines can be determined by connecting various points of electric potential or voltage.
Does inside human body considered an electrical conductor?
The inside of our body is a conductor.
Why are the equipotential lines near conductor surfaces parallel to the surface?
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.

The charge density inside a conductor is always zero
Can a static magnetic field exist in a good conductor?
A static magnetic field can exist in a good conductor. When the conductor carries current, it produces the flux which can exist inside the conductor. Due to this flux, magnetic field and intensity at a point inside the good conductor.
What is the geometrical shape of equipotential surface due to single isolated charge?
what is the geometrical shape of equipotential surface due to single isolated charge
Can two different equipotential surfaces intersect give a reason for your answer?
No, two equipotential surfaces cannot intersect. These are surfaces where the gradient of potential is zero always.

Yes. The static electric field inside a charged conductor is zero, no matter what the voltage is between the conductor and the rest of the world.
