Figure 2 Image edge detection system based on ENZ differentiator: (A) Schematic diagram; (B) Physical diagram of the system; (C) Enter the image; (D) ENZ differential generator output image; (E) MATLAB differential output image
With the support of the National Natural Science Foundation of China (approval number: 62022045, 62071272), the team of Associate Professor Li Yue of the Department of Electronic Engineering of Tsinghua University cooperated with the team of Assistant Professor Wu Jiamin of the Department of Automation and academician Dai Qionghai to realize a high-density photoelectric computing device at the sub-wavelength scale based on the near-zero (Epsilon-near-zero, ENZ) metamaterial
In view of the above problems, Li Yue et al.
The project research results provide a feasible technical solution for the miniaturization, high speed and high integration requirements of optoelectronic computing devices, and have potential application value
