Mutual Coupling Calculations between Elements on Paraboloids of Revolution

本文根据微分几何原理，从广义费马原理出发，得到了旋转抛物面上短程线的解析式，避免了数值方法射线寻迹的复杂性运用一致几何绕射理论（UTD）导出了互耦的表达式，并用近似方法（表面辐射图法（SRP）和修正表面辐射囹法（MSRP））进行了数值计算，得出了有用结果．这对旋转抛物面共形阵的分析是很重要的．

This paper presets the explicit expression of gedesic equation on a paraboloids of revolution using differential geometry which avoids the complexity of geodesic ray tracing by numerical apprcach.The mutual coupling is derived using uniform geomtrical theory of Diffraction (UTD) and then is calculated by approximate apprcaches including Surface Radiation Pattern Methed (SRP) and Medified Surface Radified Pattern methed (MSRP), which is important to the analyss of cohformal arrays.
