定向耦合器方向性英文怎么说？

Directional coupler, also known as a microwave coupler or waveguide coupler, is a passive device used in the field of microwave engineering to control and measure the power flow in a transmission line. It is specifically designed to allow power flow in one direction while isolating or attenuating the power in the opposite direction. The directional coupler consists of two or more waveguides or transmission lines that are coupled together in a specific manner to achieve this functionality. It is widely used in various applications such as power dividers, power monitors, and signal sampling. The directionality of the coupler allows for efficient power distribution and measurement in microwave systems, ensuring precise control and monitoring of signal propagation.
