Product Overview
Description
Specification
Rectangular Straight Waveguide is an important guiding wave device that uses metal tubes to transmit electromagnetic waves. The tube walls are usually copper, aluminum or other metal materials, which are characterized by simple structure and high mechanical strength. Waveguide has no inner conductor, low loss, large power capacity, electromagnetic energy is guided to spread in the inner space of the waveguide, can prevent external electromagnetic leakage.
Rectangular guided waves can transmit only TE or TM waves.

Product Description
The transmission mode of rectangular guided waves
Rectangular guided waves have degenerate mode, principal mode and single mode transmission.
Various TM and TE modes, as well as their linear combinations, can appear in rectangular guided waves. When the operating wavelength is less than the cutoff wavelength of each mode, or when the operating frequency is greater than the cutoff frequency of each mode, these modes are transmission modes, so the waveguide can form multimode transmission.
The cutoff frequency is not only dependent on the waveguide and size, but also on the medium filled in the waveguide.
The cutoff frequency is not only dependent on the waveguide and size, but also on the medium filled in the waveguide.
Transmission characteristics of rectangular guided waves
If the electromagnetic wave can be transmitted in the waveguide, it must be F > FC or λ<λ C, from which the propagation characteristic parameters of various modes of electromagnetic wave transmitted in the waveguide can be obtained.
The propagation velocity of TM wave and TE wave varies with frequency, showing dispersion characteristics.
In the case of multimode transmission in the waveguide, if the modes are orthogonal to each other, there is no energy exchange between them, and the attenuation constants of each mode can be calculated separately. If the modes are not orthogonal and have energy coupling with each other, they cannot be calculated directly alone. For each mode, in addition to conductor and medium losses, there are mode conversion losses. In a word, the factors affecting the attenuation of guided waves include the conductivity of the waveguide material, the operating frequency, the smoothness of the inner wall of the waveguide, the size of the waveguide, the loss of the filling medium, the working mode and so on.

Features
1. Rectangular waveguide cannot transmit TEM wave, only TE wave or TM wave.
2. Generally speaking, the main mode of rectangular waveguide (A > B) is TE10 mode.
3. The cutoff wavelength of rectangular waveguide is 2A.
4. The single-mode transmission condition is that the wavelength is greater than 2b and the wavelength is less than 2a and greater than A.
5. Rectangular waveguide has larger power capacity and smaller attenuation.
