Reflection - TE and TM phase plots

In summary, reflection in TE and TM phase plots refers to the phenomenon of electromagnetic waves being partially or completely reflected when encountering a boundary between two mediums. TE and TM modes have different reflection properties, which can be visualized in phase plots. These plots provide information about the reflection coefficient, phase shift, and standing wave patterns, and can be used in material characterization and practical applications such as designing microwave and optical devices. Factors such as dielectric properties, angle of incidence, and boundary nature can affect the TE and TM phase plots.

Hello everybody,

I want to confirm that the following plot is correct, especially with regards to how the phase changes after the critical angle.

The professor at my school confirms its correct, but after reviewing the relations, I get an opposite shift for the TE wave.

So can you confirm whether these plots (for n2=1.5, n1=1) are correct or not?
Thanks

in advance!Yes, the plot is correct. The phase shift for a TE wave after the critical angle is the opposite of that for an TM wave. The TE wave experiences a 180° phase shift, while the TM wave experiences a 0° phase shift.
 

Related to Reflection - TE and TM phase plots

1. What is reflection in TE and TM phase plots?

Reflection in TE and TM phase plots refers to the phenomenon where electromagnetic waves are partially or completely reflected when they encounter a boundary between two different mediums. In TE (Transverse Electric) mode, the electric field is perpendicular to the direction of propagation, while in TM (Transverse Magnetic) mode, the magnetic field is perpendicular to the direction of propagation. These modes have different reflections properties, which can be visualized in phase plots.

2. How are TE and TM phase plots different?

The main difference between TE and TM phase plots is the orientation of the electric and magnetic fields. In TE mode, the electric field is perpendicular to the boundary, while in TM mode, the magnetic field is perpendicular to the boundary. This results in different reflection coefficients and phase shifts for each mode.

3. What information can be obtained from TE and TM phase plots?

TE and TM phase plots provide information about the reflection properties of a material or boundary. This includes the reflection coefficient, phase shift, and standing wave patterns. These plots can also be used to determine the dielectric properties of a material.

4. How are TE and TM phase plots used in practical applications?

TE and TM phase plots are commonly used in the design and analysis of microwave and optical devices. They can also be used in material characterization and non-destructive testing. In addition, these plots are used in radar and satellite communication systems to analyze and optimize signal reflections.

5. What factors affect the TE and TM phase plots?

The TE and TM phase plots can be affected by various factors such as the dielectric properties of the materials, the angle of incidence, and the frequency of the electromagnetic wave. The nature of the boundary or interface between two materials also plays a significant role in the reflection properties and can impact the phase plots.
