文摘

Y-branch splitters with high efficiency at terahertz frequencies are proposed. The input channel of these splitters is a one-way waveguide. There exists no backward reflection from the junction region for incoming waves. The transmission efficiency of the splitters is perfect in the lossless case. The splitting ratio is tunable by varying the applied external magnetic field.
