Publikováno v: Photonics and Nanostructures-Fundamentals and Applications

openaire: EC/H2020/736937/EU//M-CUBE Passive electromagnetic decoupling in a very dense array of resonant active dipoles is a challenging task. Here we consider the decoupling of three very closely located resonant dipoles by two similar passive dipo
