反码:将二进制数按位取反,所得的新二进制数称为原二进制数的反码。 取反操作指:原为1,得0;原为0,得1。(1变0; 0变1) 比如:将00000000 00000000 00000000 00000101每一位取反,得11111111 11111111 11111111 11111010。 补码:反码加1称为补码。 也就是说,要得到一个数的补码,先得到反码,然后将反码加上1...
coding metasurface.Moreover,two kinds of orbital angular momentum(OAM)vortex beams with different moduli are generated by a coding metasurface using different coding sequences.Our research provides a new degree of freedom for the sophisticated manipulation of terahertz waves,and contributes to the ...
Pandas is an open-source, python-based library used in data manipulation applications requiring high performance. The name is derived from “Panel Data” having multidimensional data. This was developed in 2008 by Wes McKinney and was developed for data analysis. Pandas are useful in performing 5...

Here, we propose a design of dielectric coding metasurface with diverse functionalities, which are achieved by encoding the metasurface unit cells with different coding sequences. As proofs of concept, we demonstrate the possibility of realizing five distinct functionalities for the normal incidence of ...
