Using waveguide as input port, inside the waveguide we adopt a double antipodal fin-line transition, by adding tray and E-T junction, we can adjust the amount of the branches to get more power output.

采用波导端口输入，在波导内部使用双对极鳍线过度，通过附加托盘和E-T形结，可以灵活地调整合成路数来加大功率输出。

In one case the struggling business made a hugely speculative investment in high-fin loaches, but the sensitive fish were so traumatized by vibrations from nearby power tools that they all went belly-up in just a few days.

To simplify (a lot) the tri-gate transistor allows power to flow over three surfaces of a tall and narrow silicon fin, rather than over a flat surface.
