AI Technical Summary

⚠Technical Problem

Existing metal circular waveguides are heavy and costly to manufacture in temporary or non-standard applications, and are particularly inconvenient when a curved transmission path is required.

⚗Method used

Using ring-shaped plasma instead of circular waveguides, multiple ring-shaped plasmas are placed side by side, with the distance between the outer edges of every two ring-shaped plasmas being less than or equal to one-quarter of the waveguide wavelength corresponding to the center frequency of the internal electromagnetic wave. Ring-shaped fluorescent tubes are used to form the ring-shaped plasma, thereby achieving directional transmission of electromagnetic energy.

🎯Benefits of technology

It reduces waveguide weight, decreases processing costs, improves transportation convenience, and can replace metal circular waveguides in non-precision applications to achieve stable transmission of electromagnetic energy.

Abstract

The application discloses a method for realizing directional transmission of electromagnetic energy, and multiple annular plasmas are placed in sequence and side by side in the direction of electromagnetic wave propagation; the interval between the outer edges of each two annular plasmas is less than or equal to one quarter of the waveguide wavelength corresponding to the central frequency point of the transmitted electromagnetic wave. The application uses annular plasmas to replace circular waveguides of the same size; the annular plasmas can also be sleeved on the surface of a solid medium to form the function of a medium-filled circular waveguide; and the effect of the annular plasmas can be realized by using a lit annular fluorescent lamp, the transmission of electromagnetic waves of different frequency bands can be realized by customizing annular fluorescent lamp tubes of different sizes, the production is simple, the production cost is low, and the weight of the waveguide can be greatly reduced, so that transportation is convenient.
