slot-coupled cavity

Spectral Domain Approach Analysis of Cavity-backed Slot Array

背腔式槽阵的谱域法

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。

Characteristics of the cavity-backed narrow slot antenna in a lossy medium

背腔式窄缝天线在有耗介质中的特性

A rectangular cavity crossed slot antenna is one of ideal antenna elements for this antenna system.

矩形腔十字裂缝天线就是这种天线理想的辐射单元之一。

According to some correlative research, the backwater often happens in the aeration cavity when setting aeration bucket or slot on the base plate with slight slope.

研究发现，在小底坡的情况下设置掺气坎（槽），往往会造成掺气空腔内回水。
