In this paper, the sound field of a more general directional radiator in a stratified medium is treated, and the concept of directivity is applied to calculation of the normal modes. The result shows that the normal-mode field of a directional radiator can be obtained by supplementing the normal-mode expression of a omnidirectional point source with the directivity-excitation-function, which is dependent on the position and directivity of the radiator. In addition, the normal-mode fields of the radiators with vertical-symmetrical, vertical-antisymmetrical, single-side and sharp directivity are calculated, respectively.

本文讨论比较一般的指向性辐射器在分层介质中的声场,并将指向性概念应用于简正波计算。结果表明,对无方向性点源的简正波表示式补充以指向性激发函数,就可得到指向性辐射器的简正波声场,而指向性激发函数与辐射器的位置及指向特性有关。文中还分别计算了具有垂直对称性、反对称性、单边指向性以及尖锐指向性的辐射器的简正波声场。 对于均匀水层中的垂直线阵,若源的分布函数正比于某一简正波的本征函数,则指向性激发函数的零点正好对应于其他简正波的本征射线的方向。

Mode-field radius definitions of monomode fibers under Gaussian fitting, Gauss-exponential approximation and maximum launching efficiency are investigated both theoretically and experimentally in this paper. The suitable range of Gauss-exponential approximation has been expanded, and a new interpretation to its physical picture presented. A method in solving the multi-value problem within the expanded region has been proposed. Experimental results corresponding the three definitions are analysed and discussed, showing the widely used Gaussian fitting method might bring relatively large errors.
