研究目的
To design and analyze a high efficiency TE01-TE11 mode converter for use in systems like gyroklystrons to convert TE0n modes to the desirable TE11 mode with high conversion efficiency and mode purity.
研究成果
The designed TE01-TE11 mode converter achieves high conversion efficiency (up to 99.85%) and mode purity (up to 99.9%) with a bandwidth of 4.4% for efficiencies over 95%. It is suitable for use with gyroklystrons to generate TE11 mode and provides a foundation for further research in mode converters.
研究不足
The paper does not explicitly mention limitations, but potential areas could include the reliance on simulation without experimental validation, frequency specificity to 30.5 GHz, and possible constraints in real-world fabrication and application.
1：Experimental Design and Method Selection:
The converter is designed based on coupled wave theory using a periodic perturbation structure with a sinusoidal profile in cylindrical coordinates. The optimal configuration is a three-period converter optimized for 30.5 GHz.
2：5 GHz.
Sample Selection and Data Sources:
2. Sample Selection and Data Sources: Not specified in the paper.
3：List of Experimental Equipment and Materials:
The converter is simulated using commercial software CST; specific equipment or materials are not detailed.
