TE01-TE11 mode converter of variable-period gyroklystron
摘要
Abstract
For the shortcomings of large size and narrow band width, a variable-period serpentine circular waveguide mode converter is proposed to realize high efficiency conversion of TE01 to TE11. According to the coupled wave equation, the optimal configurations of a variable-period converter and a traditional one (their radii are all 16 mm) are respectively obtained to realize the optimal mode conversion at 30. 5 GHz. Calculation results show that the variable-period converter with a optimal length of 1 056. 97 mm, realizes a TE11 conversion efficiency of 98. 1% with its TE11 conversion bandwidth over 90% being 3. 3%. However, the traditional converter with a optimal length of 769. 53 mm, realizes a TE11 conversion efficiency of 99. 3% with its TE11 conversion bandwidth over 90% being 5. 9%. The variable-period converter assumes evident advantages in size and bandwidth over the traditional one. Test results indicate that the variable-period converter acts very well in conversion of TE01 to TE11 mode.关键词
