Circular waveguide TE11 and TM01 mixed mode diagnosis method based on eight-hole coupler

Abstract

The invention discloses a circular waveguide TE11 and TM01 mixed mode diagnosis method based on an eight-hole coupler, belongs to the field of microwave mode measurement, and aims to solve the problems that a TE11 mode is mixed in a transmission process by using a circular waveguide TM01 mode and the purity of the mixed mode cannot be measured. The average power of the eight ports of the eight-hole coupler is compared with the average power of the corresponding ends of the eight ports, it is judged that the TM01 mode is mixed with the TE11 mode under the condition that the power is not equal, and then the content of the mixed TE11 mode and the purity of the TM01 mode are judged according to the polarization angle and the mixed mode ratio. The mixed mode diagnosis method provided by the invention is simple in operation steps and obvious in experimental effect, provides a method for monitoring the mode purity of the high-power microwave system, and has the advantages of small influence of phase difference between modes, small diagnosis error, simplicity and reliability.

AI Technical Summary

Benefits of technology

This patented technology allows us to accurately detect if two different types of waves are being sent through a specific type of device called a mixer (TM). By analyzing these signals with special equipment like a tapered couplers or other devices, we found out how they were combined together during transmission. These techniques help identify any mixing patterns within certain frequencies while also measuring their power level at very low levels. They provide valuable insights into the quality control process of high-powder radar systems.

Problems solved by technology

This patented technical problem addressed in this patents relates to monitoring the quality (mode) of high power microwavages produced from different types of devices like laser diodes, magnetrons, etc., while also ensuring that they meet specific standards set forth during their manufacturers' production process. Current testing techniques can accurately measure both TE1 mode components and TE11 type ones without being able to determine if these mixes occur within acceptable limits.
