zero-index waveguide
2017/10/25
In 2015, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase o...
Complete power concentration into a single waveguide in large-scale waveguide array lenses
Complete power concentration single waveguide large-scale waveguide array lenses
