摘要
分析了波纹圆波导中由曲率所引起的模式耦合问题.从环形坐标系统中麦克斯韦方程出发导出了耦合系数的积分公式,并进一步推导了各模式间耦合系数的显式.
Mode coupling due to curvature in circumferentially corrugated circular
waveguides is analyzed in this paper. Starting from Maxwell's equations in the annular
orthogonal curvilinear coordinate-system, the integral formulae for coupling coefficients
are derived. On the basis of them, the explicit expressions of coupling coefficients between
positive or opposite modes are derived.
