In a TEM wave, both the E and H vectors are perpendicular to the direction of power flow, represented by 'S', the Poynting vector, which in turn is simply the direction in which the wave is travelling.
So neither has any component in the direction of propagation.
But are E and H necessarily perpendicular to one another?
Ex.: P = Pz ẑ
E = Ex x + Ey ŷ
H = Hx x + Hy ŷ

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
What is the explanation for the principles of electromagnetic wave?
An electromagnetic wave is properly called a Transverse Electro Magnetic wave, or TEM wave. It consists of an alternating magnetic wave at right angles to an alternating electric wave, with both fields being at right angles to the direction of propagation. The plane of the electric field is defined as the plane of polarization.
What is the formula for wave speed?
There are a few different formulas, depending on what measurements you know. For mechanical waves . . . the mechanical characteristics of the medium. For electromagnetic waves . . . the electrical characteristics of the medium. For all waves . . . the product of (wavelength) multiplied by (frequency).
Compare the process used to produce a TEM and an SEM?
The process used to produce TEM will cut cells and tissues in to ultra-thin slices so that they can be viewed under the microscope. However, the ones on SEM do not need to be cut as they can easily be visualized.
What is the different between half wave and full wave?
As states half wave will rectify only either positive or negative of a full wave. full wave will rectify positive and negative making it full wave rectification.
The waves which cannot be transmitted in waveguide are?
The Transverse electromagnetic(TEM) wave cannot be transmitted within a wave guide.

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 are the characteristics of sound waves?
The characteristics of a sound wave is the Amplitude, Frequency, Wavelength, time period, and velocity. The sound wave itself is a longitudinal wave that shows the rarefactions and compressions of a sound wave.
Which type of wave has both transverse and longitudinal characteristics?
Earthquake wave.
Light demonstrates wave characteristics when it is?
... monitored with a detector designed to detect wave characteristics. When monitored with a detector designed to detect particle characteristics, light demonstrates those too.

Does light behave primarily as a wave or as a particle when it interacts with a detector?
-- If the detector is designed to detect wave characteristics, then light exhibits all the characteristics and behavior of a wave when it encounters that detector. -- If the detector is designed to detect particle characteristics, then light exhibits all the characteristics and behavior of a particle when it encounters that detector.
Are crests and troughs characteristics of a sound wave?
No
What are characteristics of sound energy?
The main characteristics of sound are frequency, amplitude and wave length
How do you spell 'has' in Portuguese?
