Why is it important?

The results of numerical simulations show that for the total structure, spacing about 50 nm and an average transmission more than 95% is obtained. The proposed device exhibits high-transmission efficiency along with the low channel spacing. The average calculated cross talk is calculated about −18.6 dB.
