摘要

建立了在对称模TM/sub 01/和TE/sub 01/激励下的开放式圆波导辐射的数学模型。得到了易于使用和可靠的近似表达式，可以计算整个观测空间中TM/sub - 01/和TE/sub - 01/波导激励下的功率辐射方向图。数学模型是基于温斯坦提出的精确解。结果表明，TM/sub 01/和TE/sub 01/模式的近似绝对误差分别不超过0.6 dB和1.5 dB，直到-30 dB。

Mathematical model of radiation from open-ended circular waveguide excited by symmetrical TM/sub 01/ and TE/sub 01/ modes

A mathematical model of the radiation from an open-ended circular waveguide excited by the symmetrical modes TM/sub 01/ and TE/sub 01/ has been developed. Easy to use and reliable approximation expressions, which allow calculation of the power radiation pattern both for TM/sub 01/ and TE/sub 01/ waveguide excitation on the whole observation space, have been obtained. The mathematical model is based on the accurate solution developed by Weinstein. It has been shown that the approximation absolute error does not exceed 0.6 dB and 1.5 dB till the level -30 dB for TM/sub 01/ and TE/sub 01/ modes respectively.
