摘要
根据椭圆波导中电磁波的传播理论，研究并计算了任何椭圆偏心度的一系列波模的截止波长和功率衰减常数，相应地解决了椭圆波导理论中的马丢函数的精确计算问题。计算结果令人满意，并且极大地扩大了各种波模对椭圆偏心率的适用范围（１％～９９％）。
Based on the theory of the transmission of the electromagnetic waves in elliptic waveguides, the cutoff wavelength and power attenuation constant with any elliptic eccentricity are studied and theprecise calculation of Mathieu functions is appropriately resolved. The results are satisfactory and in agreement with those reported abroad. Besides, the suitable regions of changing eccentricity of variant wave modesare greatly expanded (from 1 % to 99% ).
