What does transverse mean in TEM?
A transverse mode of electromagnetic radiation is a particular electromagnetic field pattern of the radiation in the plane perpendicular (i.e., transverse) to the radiation's propagation direction.
In general, a uniform current sheet gives rise to a magnetic field perpendicular to the direction of current flow but in the plane of the sheet. Thus to generate an \(x\)-directed magnetic field, a \(y\)-directed surface current is required.
These polarizations are referred to as transverse electric (TE) and transverse magnetic (TM). This section describes these polarizations and the method for decomposition of a plane wave into TE and TM components.
Transverse magnetic (TM) modes, only the magnetic field is entirely transverse. Also notated as E modes to indicate there is a longitudinal electric component. Hybrid electromagnetic (HEM) modes, both the electric and magnetic fields have a component in the longitudinal direction.

Fiveconditions for TEM propagation in a transmission line are below. Most textbooks get the top four correct but fail to mention (5)... 1. Fields are contained in uniform,isotropic dielectric material (excludes microstrip). For TEM, there is never a calculation of Keffectiveneeded! 2. Two or more conductors are required (excludes rectangular wavegu...
Stripline provides near-TEM mode so long as it obeys the above first two rules. Let's just forget about the third and fourth rules, OK? In the figure below, the transverse directions are shown. One of these days we'll get artistic and try to draw the field lines, magnetic fields encircle the strip conductor, and electric fields extend into/out of i...
Below, we will attempt to illustrate the non-TEM behavior of microstrip Buzz Lightyear's left arm represents one electric field line directly above the microstrip conductor; his wings represent one of the magnetic field lines. As the wave propagates down the line (starting from pure TEM as it was launched by an ideal coax connector not shown), the ...
Below we've posted two movies on quasi-TEM behavior of microstrip; click on them! Contributed by Laila, thanks! Microstrip E-field magnitude Microstrip E-field vector There's more information coming soon.
This information came from Lou. There's a whole lot more coming, so check back in a week or so... Here is an approximate 3.5 mm connector with diameters of 3.5 mm outer conductor and 1.5 mm inner conductor. Never mind the square outer conductor; it just makes it easier to simulate. The first few modes are solved across the face of the coax. The dom...
Transverse components $E_{x}, E_{y}, H_{x}, H_{y}$ are expressed in terms of the longitudinal components $E_{z}, H_{z}$. And we are given three cases: 1) Transverse Electric (TE): $$ E_{z} = 0, H_{z} \neq 0$$ 2) Transverse Magnetic (TM): $$ E_{z} \neq 0, H_{z} = 0 $$ 3) Transverse Electromagnetic (TEM): $$ E_{z} = H_{z} = 0 $$
Mar 16, 2017 · TM modes have a magnetic field completely transverse to the direction of propagation, with a non-zero transverse electric field. In TEM modes both the electric and magnetic field have zero components in the transverse direction.
