waveguide aperture

A "spectral expanded BEM" is introduced to calculate the dyadic Green's functions in the slot cavity and in the space out of waveguide. An accurate numerical calculation on the slot aperture electrical field and equivalent admittance is obtained.

本文将谱展开与边界元方法相结合，解决了波导壁缝隙腔中和波导外空间并矢Green函数的计算问题，从而得到了矩形波导窄边缝隙天线口面电场和等效导纳的精确数值解。

Aperture Couplings of Waveguide The reservoir spaces of the Doushantuo Formation consist of inter crystalline pores and fracture voids.

陡山沱组的储集空间有晶间孔隙和裂隙缝洞空间。

The incline rectangular aperture antenna is one whose opening is tapered only on both narrow sides of a rectangular waveguide, placed on a perfectly infinite conducting plane, excited by the dominant H 10 mode in the rectangular waveguide.

矩形斜口面天线是把矩形波导管两个窄边同时渐削，宽边尺寸保持不变而形成的开口，口面位于无限大完全导电平面上，被矩形波导中主模H10模激励。
