We are excited to have Dr Shuyu CHEN introduce some progress on product development using acoustic metamaterial technology and discuss the new trend of commercialization of advanced material technology using metamaterials as examples.

Abstract  

The Bernstein problem asks whether entire minimal graphs in R^{n+1} are necessarily hyperplanes. It is known through spectacular work of Bernstein, Fleming, De Giorgi, Almgren, Simons, and Bombieri-De Giorgi-Giusti that the answer is positive if and only if n < 8.

Due to the physical nature of wave propagation and diffraction, there is a fundamental diffraction barrier in optical imaging systems which is called the diffraction limit or resolution limit.
