摘要： A microwave reflection filter having two waveguide channels each with a narrowing taper between the input and output ports down to dimensions which correspond with a predetermined upper cut-off frequency. The input taper of the first channel has the same dimensions as the output taper of the second channel and the input taper of the second channel is dimensioned so that the distance from the input port to the point of cut-off for any frequency in the reflected band is lambda /4 greater than the distance from the input port of the first channel to the corresponding cut-off point in the first channel.
摘要翻译：一种具有两个波导通道的微波反射滤波器，每个波导通道在输入和输出端口之间具有窄的锥形，其尺寸与预定的上限截止频率相对应。第一通道的输入锥度具有与第二通道的输出锥度相同的尺寸，并且第二通道的输入锥度的尺寸设定为使得从反射的任何频率到输入端口到截止点的距离频带是比从第一通道的输入端口到第一通道中对应的截止点的距离大的λ/ 4。

摘要： A waveguide coupler for coupling energy between a first length of waveguide capable of supporting waves of one phase velocity and a second length of waveguide capable of supporting waves having a further phase velocity has a common wall with coupling apertures between the two waveguide lengths. The waveguide length capable of supporting waves of higher phase velocity is nonrectilinear in the longitudinal direction so that an incident wave in one of the lengths is capable of coupling into the other length. The non-rectilinear length is approximately sinusoidally shaped.
摘要翻译：用于在能够支持一相速度的波导的第一长度的波导和能够支持具有另一相速度的波的波导的第二长度之间耦合能量的波导耦合器具有在两个波导长度之间的耦合孔的公共壁。能够支持较高相速度波的波导长度在纵向上是非直线的，使得其中一个长度的入射波能够耦合到另一长度。非直线长度近似为正弦形状。
