    A Hollow Rectangular Waveguide Cannot Propagate Tem Waves Because

    Waveguides are crucial components of many electronic devices, and their performance is often dependent on the quality of the waveguide. However, when a waveguide is designed improperly, it can cause problems with propagation of ultrasonic waves. In this blog post, we will explore how a hollow rectangular waveguide cannot propagate tem waves because of its design flaws.

    What is a Waveguide?

    A waveguide is an optical device that uses the principles of refraction and diffraction to guide light. The basic structure of a waveguide is a hollow rectangular or cylindrical tube with a smooth, curved surface on one end. The other end is open, allowing light to pass through the tube.

    When light travels through a waveguide, it experiences a series of reflections from the curved surface. This process causes the light to travel in a straight line along the surface of the tube. Because a waveguide can restrict the distance between the source and destination, it can be used to create extremely precise beams of light.

    One disadvantage of using a waveguide for propagation is that it cannot handle waves with large amplitudes (temporal waves). This limitation is due to the fact that waves travelling through a waveguide are restricted by its boundaries. Temporal waves are created when objects move relative to one another and generate circular patterns in space (see image below). Because a waveguide cannot propagate these types of waves, they will be reflected back into the device many times before they reach their destination.

    What are Tem Waves?

    Tem waves are electromagnetic waves with a frequency between 10 and 100 GHz. They have an unusual property that they cannot propagate through a hollow rectangular waveguide because the waveform has a pattern that is not periodic.

    How does a Waveguide Propagate Tem Waves?

    A hollow rectangular waveguide cannot propagate tem waves because the electromagnetic field travels around the inside of the channel, instead of through it.

    Conclusion

    As can be seen in the figure, a hollow rectangular waveguide cannot propagate tem waves because the electric field within the waveguide is perpendicular to thedirection of vibration.
