The proposed metasurface consists of matched helixes rotating into the corresponding helical channels allowing to modulate the reflected phase shifts of

We define a partition of the set of integers k in the range [1, m−1] prime to m into two or three subsets, where one subset consists of those integers k which are < m/2,

Estimation of the orbital angular momentum order using a vector antenna in the presence of noise.. Cheikh Dieylar Diallo, Duy Kevin Nguyen, Alexandre Chabory,

Formally prove that this equation is mass conser- vative and satisfies the (weak) maximum principle.. 4) Dynamic estimate on the entropy and the first

Figure 3b shows an alternative to such spiral phase plate, where n (due to the drilling of holes in the material) is varying linearly with the azimuthal index. Such a plate

This last step does NOT require that all indicator be converted - best if only a small percent need to be reacted to make the change visible.. Note the
