Electronic technologies, especially in the microwave and terahertz frequency ranges, including plasma show better interaction efficiency and higher output power as compared to apparatus with the vacuum. Also, in these frequency ranges, the plasma-filled high-power waveguides can support TE and TM modes. Therefore, in this study, the dispersion relation of electromagnetic (EM) waves in a new rippled-wall waveguide structure contain the plasma layer and coaxial dielectric geometry is numerically studied. The Maxwell equations and boundary conditions are employed to investigate and analyze the dispersion relation in TM mode for coaxial geometry dielectric rippled-wall waveguide contain the plasma layer. High-frequency radiations are observed from the proposed configuration. It is found that the frequency of the wave increases with a decrease in the corrugation amplitude and period. Moreover, a decrease in frequency is observed with an increase in dielectric radius and a decrease in plasma radius.

与带真空的设备相比，电子技术，尤其是在微波和太赫兹频率范围内的等离子体，显示出更好的交互效率和更高的输出功率。同样，在这些频率范围内，充满等离子体的高功率波导可以支持TE和TM模式。因此，在本研究中，对包含等离子体层的新型波纹壁波导结构中电磁波的色散关系进行了数值研究。利用麦克斯韦方程和边界条件，研究和分析了包含等离子体层的同轴几何介质波纹壁波导在TM模式下的色散关系。从建议的配置中可以观察到高频辐射。发现波的频率随着波纹幅度和周期的减小而增加。此外，随着介电半径的增加和等离子体半径的减少，观察到频率降低。
